Sarthi is an epithet of Krishna (an Avatar of Vishnu) in the Mahabharata, a farmost important Hindu historical epic. It is also a common name in some parts of India.
In the Mahabharata, Krishna counselled the Pandavas and Karuravas, two closely related families fighting over a kingdom in northern India.
