Bahulā (also known as Bahulā-caturthī) is one of the minor festivals observed in the northern parts of India on the fourth day of the dark fortnight (kṛṣṇa-caturthī) of the month of Bhādra (September). It is generally observed by women who have children. After the usual fasting and prayers as prescribed for such festivals, a cow with a calf is worshipped in the evening and also offered some sweets in an earthen pot. Fast can be broken only after that, with cooked barley. An observance of this festival with its vows is said to confer children and wealth on the votary.
This festival is connected with two folk tales: A cow was caught by a hungry lion, begged the lion to allow it to feed its little calf at home and then return. The lion obliged and the cow returned, true to its promise. Moved by its devotion to truth, the lion let it go. It was on this day that the truthful cow was liberated by the lion.
A lady, Vipulā by name, took the dead body of her young husband on a raft by a river called Bahulā, to the world of the serpent goddess Manasā and got him revived on this day. Hence, listening to this story on this day gives religious merit.
