What is Parivartana Yoga?
Parivartana Yoga (mutual reception) forms when the lords of two houses sit in each other's signs, tightly linking those two houses. Maha Parivartana links good houses (1, 2, 4, 5, 7, 9, 10, 11) and is strongly auspicious; Dainya Parivartana involves a dusthana (6, 8, 12) and is more challenging.
