When a proud King Trisanku asked his Guru Vashista to send him to heaven in his own body, guru responded that the body cannot ascend to heaven. King Trisanku then asked Vashista's hundred sons to send him to heaven. The sons, believing that Trisanku should not come to them after their father had refused, took outrage and cursed Trisanku to be a Chandala. Trisanku was transformed into a person with body smeared of ash, clothed in black and wearing iron jewelry. Unrecognizable to his subjects, he was driven out of the kingdom.
