Maraṇakārakasthāna (MKS) is a concept primarily from Jaimini astrology, referring to the house placement where each planet is at maximum affliction — unable to express its natural qualities. The MKS positions are: Sun in 12th, Moon in 8th, Mars in 7th, Mercury in 7th, Jupiter in 3rd, Venus in 6th, Saturn in 1st, Rahu in 9th, Ketu in 6th. A planet in its MKS is not necessarily always negative — when it rules a beneficial house, its placement in MKS can create powerful transformations in Jaimini's Chara Dasha system, particularly when involved in yogas. The concept is important in understanding chart imbalances.
