Hamsa yoga
Hamsa yoga, one of the five Mahapurush yogas, forms when Jupiter is in Sagittarius, Pisces or Cancer and in a kendra (the 1st, 4th, 7th or 10th house). It is linked with wisdom, ethics and respect.
Also known as: Hans yoga, Hamsa yog, Jupiter Mahapurusha yoga, Guru Mahapurush yoga
Jupiter rules Sagittarius and Pisces and is exalted in Cancer. In one of those signs, in a kendra from the ascendant, it forms Hamsa yoga, named after the swan, a symbol of discernment. Classical texts describe a righteous, learned and well-regarded person, drawn to teaching, law, finance, counselling or spiritual work.
Its gifts are judgement and goodwill rather than sudden gain. It tends to show most clearly in Jupiter’s 16-year dasha, and it is strongest when Jupiter is not combust and is supported in the Navamsa.
One subtlety: for Gemini and Virgo ascendants, Jupiter rules two kendras, which classical texts treat as a mixed role for a natural benefic (kendradhipati dosha). The yoga still forms, but an astrologer weighs both sides.
