The Mahabharata Anushasanaparva Chapter 71 has a mention of another sage named Uddalaka. Once this sage forgot his flowers, pot and food on the banks of the river and proceeded to his hermitage. He remembered it when he got there and asked his son Nachiketa to fetch them. But by the time Nachiketa got there, the river had carried it away. He reported this to his father, who in a fit of anger cursed him dead. But he soon repented and his tears brought back Nachiketa to life. Uddalaka asked his son to describe  Yama’s world and his son gave him all the details.
