The Mahabharata of Krishna-Dwaipayana Vyasa…
“ Possessed of great ascetic merit, he wished to install his son Vishvamitra on his throne, himself having resolved to cast off his body. His subjects, bowing unto him, said, 'Thou shouldst not go away, O thou of great wisdom, but do thou protect us from a great fear!' Thus addressed, Gadhi replied unto his subjects, saying, 'My son will become the protector of the wide universe!' Having said these words, and placed Vishvamitra (on the throne) , Gadhi, O king, went to heaven, and Vishvamitra became king. He could not, however, protect the earth with even his best exertions. ”
