As per Hindu scriptures, people worship Goddess Sasthi, the goddess of children and fertility, on this day. A popular folktale says a housewife once wrongly blamed the goddess's vehicle, a cat, for theft. The angry goddess took away her child, but returned him after the housewife observed a strict fast to please her.

This festival is also called 'Aranya Sasthi'. In the old days, people would worship nature by creating a symbolic representation of a forest or performing the rituals inside a forest.

On Jamai Sasthi, mothers-in-law follow several rituals with great devotion. They wake up early, bathe, wear new clothes, and perform the puja for Goddess Sasthi. When the son-in-law arrives, they welcome him with an aarti and apply a sacred tilak of curd or sandalwood on his forehead. They also tie a holy yellow thread from the puja on his wrist and bless him with paddy and durva grass.

Following an old tradition, the mother-in-law fans her son-in-law with a new palm-leaf fan, chanting "Shaat-shaat-shaat" three times to wish him a long and protected life. This day also involves exchanging gifts. The son-in-law receives new clothes or other valuable items, and he, in turn, brings sweets, fruits, and gifts for the in-laws.
