Drekkana Chart (D3): Siblings, Courage, and the 3rd-Division Chart

Quick Answer: The Drekkana (द्रेक्काण) is the third divisional chart in Vedic astrology, formed by splitting each 30° rashi into three equal 10° portions and remapping the planets into the signs assigned to those portions. Classically it is the chart of siblings, co-borns, and self-made courage — the inner faculty of parakrama that the 3rd house signifies in the Rashi chart. A serious reading on brothers and sisters, on personal initiative, or on the kind of valour native to a chart eventually turns from D1 to the D3 for confirmation.

What Is the Drekkana (D3) Chart?

The word Drekkana (द्रेक्काण, also spelled drekkānam or drekkana) is a Sanskrit compound that the classical commentators trace to a root meaning "three parts." Whatever the precise etymology one accepts, the name already announces what the chart does: every Rashi of the natal sky is taken apart into three equal portions, and the planets are then read through the new signs those portions are assigned to. The arithmetic is fixed, the procedure is deterministic, and yet the chart it produces has carried a specific weight in Vedic practice for at least two millennia — the chart of siblings, courage, and self-effort.

That weight is not accidental. The Drekkana sits in the Parashari scheme of sixteen divisional charts as the third Varga, and Jyotish tradition is unusually consistent in mapping the third division onto the third house. The 3rd Bhava in the Rashi chart is the पराक्रम (parakrama) Bhava — the house of valour, younger siblings, short journeys, communication, and the personal effort that pushes a life forward when no inherited support is doing the work. The third division of each Rashi carries that same signification one layer deeper, and the D3 is read as the divisional witness for everything the 3rd house already promises.

The Greek "Decan" Connection

The Drekkana has a surprisingly long international biography. The threefold division of each zodiacal sign appears not only in the Vedic Parashari tradition but also in the older Egyptian and Hellenistic star-charts, where the same ten-degree slice was known as a decan. According to scholarly accounts on the decan in Greco-Egyptian astronomy, these were ten-degree segments of the ecliptic used to mark the hours of the night long before they were absorbed into horoscopic interpretation.

That connection matters for honesty. When Indian Jyotish texts speak of the Drekkana, they are working with a division that is at once mathematically natural (any 30° span divides cleanly into three 10° segments) and historically widespread. The Vedic tradition gave the Drekkana a meaning the older decan tradition did not — siblings, courage, the inner faculty of effort — and built around it a deity-and-ruler system the Greek tradition lacked. But the underlying arithmetic of "each sign in three" is shared, and acknowledging that lineage prevents the chart from feeling like a piece of esoteric machinery unique to a single school.

Why the Third Division, Specifically

Threefold division is one of the most quietly powerful gestures in classical Vedic thought. The three gunas — सत्त्व, रजस्, तमस् — describe every quality of the manifest world in three modes. The four classical movable-fixed-dual sign categories rest on a triadic instinct about how energy initiates, holds, and adapts. So when Parashara takes each Rashi and cuts it into three equal portions, the cut is not arbitrary; it is the same gesture by which Vedic philosophy has always divided the qualitative field of experience.

The D3 carries that instinct into the chart. Where the Rashi chart shows the broad arena of a life, the Drekkana asks how the threefold quality of each sign is actually distributed within it — the first portion staying close to the sign's own nature, the second moving five signs forward into a related expression, the third moving nine signs forward into the most distant reach of the same elemental triad. The mathematics and the symbolism, in other words, point at the same place: a chart that reads the inner gradations of will, effort, and shared blood.

How the Drekkana Is Mathematically Constructed

The Drekkana is built from the same Swiss Ephemeris longitudes used to draw the Rashi chart. The construction adds two ingredients to those numbers: a threefold split of each sign, and a fixed rule that tells you which sign each of the three portions is assigned to. Once those two ingredients are in place, the rest is arithmetic. No astrological judgement is required to derive a planet's Drekkana sign — judgement only enters when the resulting chart is read.

The Three-Part Division Rule

Each 30° Rashi is cut into three equal portions of 10°. The first drekkana runs from 0°00' to 10°00'. The second runs from 10°00' to 20°00'. The third runs from 20°00' to 30°00'. Every planet, by virtue of its degree within its Rashi, falls into exactly one of these three portions, and that portion number is the bridge between the D1 sign and the D3 sign.

A planet at 4° Aries falls in the first drekkana. A planet at 14° Aries falls in the second. A planet at 24° Aries falls in the third. The Lagna itself is treated the same way; the degree of the Ascendant in its Rashi tells you which drekkana the chart begins from, and the D3 Lagna follows from that.

The Starting-Sign Rule (Parashari)

Knowing the portion is not enough. We also need to know which sign each of the three portions is mapped to. The classical Parashari rule preserved in the Brihat Parashara Hora Shastra assigns the three drekkanas of any sign as follows:

• First drekkana (0° to 10°) — the sign itself.
• Second drekkana (10° to 20°) — the fifth sign from the original, counted inclusively.
• Third drekkana (20° to 30°) — the ninth sign from the original, counted inclusively.

The three signs produced by this rule are not random. The first, fifth, and ninth signs from any given Rashi always share the same element — fiery signs map to fiery, earthy to earthy, airy to airy, watery to watery. This is the same trinal pattern that gives the chart its त्रिकोण (trikona) houses their dharmic weight. The Drekkana's mathematical signature, in other words, is elemental coherence: a planet that shifts from D1 to D3 always stays inside the same elemental family.

A Worked Example

Suppose Mars sits at 17° Leo in the Rashi chart. Three small steps deliver its Drekkana sign without ambiguity.

First, identify the drekkana portion. 17° Leo lies between 10°00' and 20°00', so Mars occupies the second drekkana of Leo. Second, identify the starting sign. Leo's first drekkana is Leo itself; its second drekkana is the fifth sign from Leo. Counting inclusively from Leo — Leo (1), Virgo (2), Libra (3), Scorpio (4), Sagittarius (5) — the second drekkana of Leo is Sagittarius. Third, place the planet. Mars at 17° Leo in D1 sits in Sagittarius in the D3.

The interpretive shift is real. Mars in Leo in D1 expresses fiery initiative through Leonine self-presentation: visible courage, performance, the will of a leader. Mars in Sagittarius in D3 carries the same fiery initiative, but its inner register changes — courage now reaches for meaning, ethics, distance, the kind of valour that travels rather than the kind that performs.

Drekkana Reference Table

Worked out for all twelve signs, the Parashari rule produces the following compact table. Read it as the fixed map from D1 sign to D3 sign by drekkana portion:

Reading the table aloud confirms the elemental rule. Every row lists three signs of the same element, beginning from the sign itself and stepping through its trinal companions. This is why classical authors call the Drekkana a "self-coherent" division: a planet never leaves its elemental family on the way from D1 to D3.

Why D3 Reveals Siblings, Co-Borns, and Courage

A reader new to Vedic astrology often wants a single reason why a particular Varga is read for a particular life-area. The Drekkana is one of the cleanest cases. The third division of each Rashi maps onto the third Bhava of the Rashi chart, and the third Bhava is, in the consensus of every Parashari author, the house of siblings, valour, short journeys, communication, and self-effort. The match is structural rather than interpretive.

This kshetra-level correspondence is why classical compilations consistently assign the Drekkana to questions about सहोदर (sahodara) — co-borns and especially younger siblings — and to parakrama, the inner faculty of effort that the 3rd house signifies. The same logic applies further down the Varga ladder; the seventh division is read for spouse because the seventh Bhava is the house of partnership, and the tenth division is read for career because the tenth Bhava is the house of profession. The Drekkana is part of that family pattern.

Classical Citations

Parashara's Brihat Parashara Hora Shastra, the foundational compendium of Parashari Jyotish whose surviving recensions are described in the scholarly literature on the text, names the Drekkana among the sixteen Vargas and assigns it to siblings and to the strength of the 3rd Bhava's significations. Mantreshwara's Phaladeepika, a later but widely used Parashari manual, retains the same allocation and adds practical reading rules for the D3 with respect to bhratri sukha, the well-being of brothers.

The Jaimini school, whose technical apparatus differs from Parashari in many respects, also retains the Drekkana as a chart consulted for kindred and effort, though its method of reading it (through karakas and chara dashas) is its own. What is consistent across the schools is the meaning attached to the chart, not the technique used to read it. Sibling-questions and courage-questions, in the broader Jyotisha tradition, are eventually D3 questions.

What "Co-Born" Includes in Practice

The Sanskrit term sahodara literally means "born of the same womb," and the conservative reading of the Drekkana restricts the chart to biological siblings. Practical Jyotishis often extend the meaning further, especially in modern charts where blended families, half-siblings, and chosen kin are common. The defensible extensions are these:

• Biological siblings, both elder and younger, are the canonical signification. Younger siblings sit specifically with the 3rd house and the 3rd lord; elder siblings are read additionally through the 11th house and Jupiter as karaka.
• Half-siblings and step-siblings are accommodated as variations of the same sibling-field, often with a Drekkana that shows mixed dispositors or split rulerships.
• Cousins and close kin raised as siblings are read through the same indicators, especially when the 3rd house carries strong Mars-Mercury influence.
• Chosen sibling-bonds — close friends or comrades who function as brothers — are not classical but are routinely accommodated by modern readers when the D3 shows strong friendly placements in the houses of companions.

The classical injunction against counting siblings from D3 alone applies to all of these. The chart witnesses the quality of the sibling relationship and the courage native to the chart; it is not a counting device. A later section will return to this distinction.

The Karaka Layer

The Drekkana is read with two natural karakas in mind. Mars (मंगल) is the karaka for siblings as a whole, and especially for valour and the inner faculty of effort. Mercury (बुध) is the karaka for younger siblings specifically, while Jupiter (बृहस्पति) is the karaka for elder siblings as protectors and as carriers of dharmic example. A Jyotishi reading the D3 will check all three karakas in the divisional chart, not only the third house and its lord. Where the karaka is strong in D3, the signification it carries — courage, younger sibling, elder sibling — is supported. Where the karaka is afflicted, the signification weakens in inner quality even if the outer fact (the existence of a sibling, the occurrence of an act of courage) remains.

Reading the Drekkana: What to Look At

When a Jyotishi turns from D1 to D3, the questions shift from "what does the chart promise about siblings and effort?" to "does that promise hold in the divisional witness?" The Drekkana is read in the same disciplined order that any divisional chart is read: Lagna first, then the house that signifies the topic, then the lord of that house, then the karaka. The order is not decorative — each step refines the picture the last one left behind.

The Drekkana Lagna

Just as the D1 begins with the Ascendant, the D3 has its own Lagna. The Drekkana Lagna is derived from the exact degree of the D1 Ascendant placed inside its drekkana portion and mapped to the corresponding starting sign. This Lagna gives the D3 its own house structure, and it is from this new Lagna — not from the D1 Lagna — that the D3 houses are counted.

Reading the Drekkana Lagna for temperament is a small but important step. The Ascendant of the D3 describes the inner courage-temperament that the chart carries: how the native meets pressure, whether their default response to challenge is initiative, persistence, or retreat, and what kind of sibling-energy they radiate to those around them. A strong Drekkana Lagna, well-aspected and untenanted by malefics, suggests a steady inner stance under stress. A weak one suggests that visible courage in D1 may not have a comfortable inner ground in D3.

The 3rd House and Its Lord in D3

The single most important placement in the Drekkana is the third house of the D3 itself, counted from the Drekkana Lagna, and the lord of that third house. Together they tell us the divisional quality of siblings and parakrama. A 3rd lord in a Kendra or Trikona of the D3 promises supportive co-borns and reliable courage; a 3rd lord in a Dusthana suggests strain in sibling relationships or hesitation in effort. The same logic governs occupants of the third house: a benefic occupant strengthens the bond, a malefic without redeeming dignity often shows friction.

The Jyotishi also checks the dispositor of the third lord. If the dispositor itself is well-placed, the 3rd lord's significations gain a second layer of support. If the dispositor is wounded, the 3rd lord may show good results in flashes but lose their continuity.

Mars in the Drekkana

Mars is the chief karaka of the chart, and the Drekkana is among the few divisional charts where Mars deserves a fuller reading than the Rashi gives it. A Mars exalted or in own sign in D3, particularly when placed in a Kendra or Trikona, is one of the strongest classical signatures for both courage and supportive co-borns. The same Mars in debility or in a Dusthana of the D3 typically shows hesitation in initiative, conflict with siblings, or both — even when the D1 Mars looks acceptable.

Mercury, Jupiter, and the Lord of Each Drekkana

Mercury and Jupiter complete the karaka layer. Mercury speaks for younger siblings and for the witty, communicative side of parakrama. Jupiter speaks for elder siblings and for the protective dharmic example that an elder sibling can carry. Each is checked in D3 for the same questions: dignity, house placement, aspects, and the dispositor's condition.

A subtler but classical move is to read the drekkana lord for each planet — the ruler of the sign the planet falls into in the D3. The drekkana lord is the secondary disposing influence on the planet's expression in the divisional sky. Where the drekkana lord is well-placed in the D3, the planet's signification finds an inner channel. Where the drekkana lord struggles, the planet may express itself unevenly even when its own divisional sign looks dignified.

Aspects in D3

Aspects are computed in the Drekkana using the same Vedic दृष्टि (Drishti) rules as in the Rashi chart — the 7th-house aspect for all planets, the special aspects of Mars, Jupiter, and Saturn — but the houses are counted from the Drekkana Lagna. An aspect of Jupiter on the D3 3rd lord, for example, is read as benefic protection over siblings and effort. A Saturn aspect without dignity is read as friction that demands maturity. The Jyotishi avoids over-interpreting D3 aspects in isolation; each is checked back against the D1 to see whether the same planet is also commenting on the third house in the Rashi chart.

Reading D1 and D3 Together

A Varga chart is meaningful only in relation to the Rashi chart that produced it. The Drekkana is no exception. Reading D1 and D3 together is not a mechanical averaging of placements; it is a disciplined cross-check that asks whether the visible promise of the Rashi chart finds inner support in the divisional sky. The Jyotishi reads D1 first to identify what is promised, then turns to D3 to ask whether that promise has roots.

The Core Interaction Matrix

Four broad situations cover most readings on siblings and courage. Each combines a D1 condition for the 3rd house, its lord, or Mars with the corresponding D3 condition, and produces a characteristic interpretation. The table below gives the basic pattern:

Vargottama placements deserve a separate note. When a planet occupies the same Rashi in both D1 and D3, it is treated as Vargottama in the Drekkana — a placement classical authors regard as particularly stable. Mathematically this happens only in specific spans, mirroring the Vargottama rule of the Navamsa but for the threefold division: 0°00'-10°00' of any sign always produces same-sign Vargottama in D3, since the first drekkana of every sign is the sign itself. A planet in the first ten degrees of its Rashi is automatically Vargottama in the Drekkana, and a Jyotishi reading sibling-questions for such a chart begins with that as a strong baseline signal.

Confirming Sibling Indications Across Both Charts

A working rule in practice is to ask three confirmation questions before pronouncing on siblings. First, what does the D1 third house and its lord show? Second, does the D3 third house, its lord, and Mars repeat the same message? Third, where is Mercury for younger siblings, and Jupiter for elder? When all three layers agree, the reading is robust. When they disagree, the Jyotishi names the disagreement rather than averaging it: outer sibling-presence with inner distance, or absence of sibling in the visible record with strong inner companionship from cousins or close friends.

Practical Examples

Consider a chart where Mars sits at 4° Cancer in D1 — debilitated in a watery sign of cardinal initiative, classically a weak placement for courage. In the D3, the first drekkana of Cancer is Cancer itself, so the same Mars remains in Cancer in D3 and is therefore Vargottama. The Rashi reading would have flagged debility; the Drekkana reading qualifies the verdict. The native may show emotionally hesitant courage on the surface, but the same hesitancy holds its shape across both charts. That consistency is itself a strength. Vargottama debilitated Mars often describes a person whose courage is quiet, persistent, and centred on protecting kin rather than performing in public.

Contrast this with a Mars at 17° Leo, the worked example from the construction section. In D1 Mars is in its friend's sign with confident self-presentation; in D3 Mars moves to Sagittarius, a fiery sign of meaning and travel. The D1 promises visible courage; the D3 promises that the same courage will mature into ethical or expansive direction over time. A useful additional dimension comes from the 3rd house article in the Houses and Bhavas series, which discusses what parakrama means as a lived faculty.

Drekkana and the Inner Quality of Courage

The English word "courage" carries less in it than the Sanskrit parakrama. Para-krama is the stepping-forth of one's own foot — the action one takes oneself, without inheritance, without waiting for sanction. Where the second house signifies the wealth and family one is born into, the third house signifies what one does with one's own arm. The Drekkana, being the divisional witness to that third house, becomes the chart of self-made strength.

This distinction between inherited and self-made strength is the most important interpretive frame for the D3. Some charts show a person whose visible advantages come from family — the second house is strong, the lineage supportive. Other charts show a person whose visible advantages come from their own effort, the third house and its lord doing the work the second house could not do. The Drekkana refines the picture further by asking what kind of courage the chart is actually drawing on.

Kinds of Courage the Drekkana Distinguishes

Reading the D3 carefully, classical Jyotishis tend to recognise several distinct kinds of valour, each associated with a particular element and karaka pattern. The list below is not exhaustive, but it sketches the qualitative range a Drekkana can describe:

1. Fiery courage — Mars-led, expressed as initiative, leadership, willingness to be the first to move. Often shown by a strong fiery Drekkana Lagna or by a powerful Mars in D3. The risk-pattern is impatience.
2. Earthy courage — endurance under prolonged pressure, the courage of farmers, builders, parents. Shown by earthy Drekkana placements and by a steady Saturn in the D3. The risk-pattern is rigidity.
3. Airy courage — the courage of speech, of standing for an unpopular truth, of comradeship. Shown by airy Drekkana placements and by a strong Mercury or Venus in D3. The risk-pattern is dispersal.
4. Watery courage — the quiet courage of protection, of caring for the wounded, of refusing to abandon one's kin. Shown by watery Drekkana placements and by a strong Moon or Jupiter in D3. The risk-pattern is over-attachment.

None of these is "higher" than the others. A serious reading names the kind of courage a chart carries rather than measuring it against a single ideal. A fiery chart that tries to be quietly enduring will exhaust itself; a watery chart that tries to be publicly impatient will burn out faster still. The Drekkana, by showing where the elemental weight sits in the third division, helps the Jyotishi guide the reader towards the courage that is actually native to them.

Self-Made versus Inherited

One of the more useful classical distinctions the Drekkana enables is the contrast between inherited and self-made strength. When a chart shows a powerful second house but a weak third — or a strong D2 but a strained D3 — the native may have considerable family advantage that nevertheless does not translate into independent personal courage. The achievements are real but borrowed; the chart relies on inheritance to perform.

The reverse pattern is at least as common and often more interesting. A chart with a modest second house but a strong third house, and a Drekkana that confirms the same, describes a person whose strength is genuinely their own. The early years may show no inherited advantage; the later years show a settled inner stance that does not need the second house's external scaffolding. This is the classical reading of parakrama, and the Drekkana is the chart that confirms it.

The Connection to Brothers as Allies

Classical authors often note that siblings, when supportive, function as the natural ground of parakrama. A brother who walks beside one through early effort is read in the same chart as the courage that effort requires. This is not sentimental — it reflects the lived observation that personal initiative is often easier in the presence of co-borns who back the effort.

The D3 carries both meanings together. A strong third lord in the Drekkana, well-aspected and undisturbed, often shows a chart in which siblings and courage reinforce each other: the bond with brothers and sisters strengthens the inner faculty of effort, and the effort in turn deepens the bond. A weak third lord shows the opposite tension. The kin-line and the inner faculty have to be cultivated separately, and the reader is asked to recognise the work that requires.

Practical Cautions and Common Mistakes

The Drekkana is a powerful chart, but most of the errors readers make with it come from over-interpreting it in isolation or from asking it questions it was never designed to answer. The cautions below collect the most common mistakes and explain the disciplined way to avoid them.

Never Predict the Number of Siblings from D3 Alone

The most persistent misuse of the Drekkana is to count siblings by counting planets in or aspecting the third house. Classical authors are explicit that the D3 is a chart of quality, not quantity. The number of siblings a person actually has is shaped by social, biological, and family-planning realities that are not isolable in any chart. What the Drekkana describes is the quality of the sibling bond, the type of co-born the chart attracts, and the inner courage native to the chart.

A Jyotishi who tries to derive a precise sibling-count from the D3 will sooner or later embarrass themselves. The defensible move is to describe the sibling-field — supportive or strained, elder or younger weighted, biologically present or substituted by close kin — and to leave counting to demographic reality.

Apply Karaka-Bhava-Vichara

The classical procedure for any house-related question is कारक भाव विचार (karaka-bhava-vichara) — read the house, then read the lord of the house, then read the karaka. For siblings and courage the karakas are Mars, Mercury, and Jupiter, as discussed earlier. Skipping the karaka layer is the second-commonest mistake with the Drekkana.

The disciplined order is therefore: (a) read the third Bhava in D1 and D3; (b) read the third lord's placement and dispositor in both; (c) read Mars for courage and overall sibling-presence, Mercury for younger siblings, Jupiter for elder. A signal that appears across the house, the lord, and the karaka is the only kind a serious reading should rely on. A signal that appears in just one of the three is provisional and should be flagged as such.

Do Not Use D1 Houses to Read the D3

Each divisional chart has its own Lagna and therefore its own house structure. A common beginner error is to look at the planets in the D3 but to count their houses from the D1 Ascendant. Houses in the Drekkana are counted from the Drekkana Lagna. If the D1 Lagna is Aries and the D3 Lagna is Leo, the third house of the D3 is Libra, not Gemini. A Jyotishi who confuses the two readings will arrive at conclusions that contradict the chart itself.

Do Not Read the D3 Without the D1

The Drekkana is a divisional witness, not a standalone chart. A planet's significations are anchored in the Rashi chart it came from; the D3 refines and tests those significations rather than replacing them. Reading the Drekkana as if it were a second birth chart leads to the same kind of error as reading the Navamsa in isolation — dramatic-sounding conclusions detached from the chart's actual promise.

The working rule is to begin with D1 for the broad sibling-and-courage picture, then turn to D3 to ask whether that picture has roots. If the two charts agree, the reading is robust. If they disagree, the Jyotishi names the disagreement and explains what the divergence likely shows. For a wider treatment of how divisional charts interact with the Rashi chart in general, our complete guide to the divisional charts walks through the full sixteen-Varga framework, and our article on Lagna versus Navamsa is the closest sibling-discussion to this one in the series. A deeper treatment of the same Parashari sky from the soul's-second-chart angle is available in our Navamsa D9 deep dive.

Beware the Single Dramatic Contrast

An exalted planet in D1 that falls to debility in D3 is striking on first reading, but a serious Jyotishi tempers the drama by asking three questions. Is the planet a chart-anchor — Lagna lord, third lord, or a strong Dasha lord? Is the same planet supported by a friendly aspect in D3 that softens the debility? Does Vargottama status apply elsewhere in the chart to balance the picture? A single dramatic D1-to-D3 contrast becomes meaningful only when the chart as a whole confirms the message. Otherwise it is best read as one signal among several, and the reader should know it.

Frequently Asked Questions

What does the Drekkana (D3) chart show in Vedic astrology?

The Drekkana is the third divisional chart in Vedic astrology, formed by splitting each 30° rashi into three equal 10° portions. It is read for siblings, co-borns, the inner faculty of courage (parakrama), short journeys, and personal effort. Classical Parashari texts including the Brihat Parashara Hora Shastra map the third division onto the third house of the Rashi chart, which gives the D3 its specific significations.

How is the Drekkana chart constructed?

Each Rashi is divided into three 10° portions. By the classical Parashari rule, the first drekkana of any sign maps to the sign itself, the second drekkana to the fifth sign from the original (counted inclusively), and the third drekkana to the ninth sign from the original. The three signs produced always share the same element. A planet's degree within its Rashi tells you which drekkana it occupies, and the rule then gives its D3 sign.

Can I predict how many siblings I have from the D3?

No. The Drekkana shows the quality of the sibling-bond, the type of co-born the chart attracts, and the inner courage native to the chart. It is not a counting device, and classical authors are explicit that the actual number of siblings depends on social, biological, and family-planning realities that are not isolable in any chart. A serious reading describes the sibling-field rather than counting it.

What is parakrama, and how does the D3 relate to it?

Parakrama is the Sanskrit term for self-made effort — literally the stepping-forth of one's own foot. It is the courage that does not depend on inheritance or sanction. The third house in the Rashi chart signifies parakrama, and the Drekkana, as the third divisional chart, is read as the divisional witness to that faculty. A strong D3 third house, third lord, and Mars together describe a chart in which personal initiative finds inner support; a weak D3 shows a courage-faculty that has to be cultivated rather than assumed.

How does the Drekkana relate to the Greek decan?

The threefold division of each zodiacal sign appears not only in the Vedic Parashari tradition but also in older Egyptian and Hellenistic astronomy, where each ten-degree segment was known as a decan. The underlying arithmetic of "each sign in three" is shared across these traditions. The Vedic Drekkana, however, attaches a meaning — siblings, courage, parakrama — and a system of deities and rulers that the Greek decan did not carry.
