Dvisvabhāva (dual/mutable) signs are the four rāśis that fall at the end of each season, transitioning into the next: Mithuna (Gemini) at the end of spring, Kanya (Virgo) at the end of summer, Dhanu (Sagittarius) at the end of autumn, Meena (Pisces) at the end of winter. They are characterized by adaptability, flexibility, and a dual nature that sees multiple sides. The badhaka (obstructor) house for dwiswabhava lagnas is the 7th house. Planets in dual signs tend to give variable results — they can swing between extremes or express both the qualities of the sign they are leaving and the one they are entering.
