Upamanyu is a Rigvedic rishi. He is said to be the father or ancestor of sage Kamboja Aupamanyava referred to in the Vamsa Brahmana of the Sama Veda. Once Krishna went to him to take advice as Jambavati (Krishna’s wife) wanted a son like Pradyumna. On his advice Krishna starts to pray to the god Shiva. After many months, Shiva finally appears before Krishna. Krishna then soughts a son from Jambavati, which was granted by Shiva.
