Avataars of Lord Shiva
Upamanyu the son of sage Vyaghrapaad, was brought up in his maternal uncles home since his childhood. One day Upanyu he was crying for milk when his mother told him that if he wanted milk then he should worship lord Shiva as he only was capable of making the milk available. Upamanyu proceeded towards the Himalaya and started doing penance to please lord Shiva. His penance generated so much of heat that all the three worlds started burning.
