Sthira (fixed) signs are the four rāśis that fall in the middle of each season, when that season's qualities are most stable: Vrishabha (Taurus) in mid-spring, Simha (Leo) in mid-summer, Vrishchika (Scorpio) in mid-autumn, Kumbha (Aquarius) in mid-winter. They are characterized by determination, persistence, and resistance to change. Planets in sthira signs tend to give steady, enduring results that are slow to manifest but long-lasting. The badhaka (obstructor) house for sthira lagnas is the 9th house. Fixed signs are associated with accumulation — of wealth, knowledge, or karmic patterns.
