The Ashvamedhika Parva narrates Uttanka's meeting with the god Krishna. As Krishna was returning to his kingdom Dwarka, he noticed the wandering ascetic Uttanka. Uttanka met Krishna and asked for news. Krishna told about the devastation in the Kurukshetra War. Uttanka was agitated and was about to curse Krishna for not bringing about a compromise between the warring cousins Pandavas and Kauravas. Krishna explained the necessity of war for restoration of dharma and revealed his Vishvarupa form to Uttanka. The sage bowed to Krishna. Krishna told Uttanka to ask for a boon. Uttanka asked Krishna to grant him the boon of finding water whenever he was thirsty. Krishna granted the boon to Uttanka.[1][10] Uttanka was one of the blessed people to have had an opportunity to see Sri Krishna's vishvarupa. The other people who also had this privilege were Akrura, Arjuna, Dhritarashtra, Sanjaya, Yashoda and Veda Vyasa.
Wandering in the desert, the sage became thirsty and, hoping to get water, thought of Krishna, who gave order Indra and asked him to give amrita to Uttanka but Indra was not willing to give it to mortals. In the end, Indra had told Krishna that he would offer Uttanka the amrita as a Chandala, provided the sage did not refuse it. Krishna had agreed to Indra's condition. Indra appeared as hunter called Chandala but Uttang refused to take water from him and he disappeared. Uttanka, realizing his mistake that ordinary men cannot appear in this desert, either he was a Deva or messenger of Krishana. So Uttanka started to finish himself, Then when Krishna appeared on the scene and stopped him to burn his body by Tapa, Krishna explained that he had requested Indra to give him amrita, Krishna then informed Uttanka that his refusal to accept amrita from the Chandala was improper. Finally, Indra had relented and had told Krishna that he would offer Uttanka the amrita as a Chandala, provided the sage did not refuse it. Krishna had agreed to Indra's condition. Krishna promised to keep his boon of providing water to the sage. He then blessed Uttanka that rain clouds would appear at his bidding and bring rain showers in the desert. These clouds appear rarely, and in the desert rain clouds are still known as Uttanka's clouds
