Jaratkaru

Jaratkaru was a sage engaged in sever penances. Lost in meditation, he would roam around the forests, unclothed.
One day he saw a huge pit in the forest. A root of a tree was covering the pit, and from the root were hanging some sages.
Jaratkaru asked them who they were and why they hanging like this. He also told them that a forest rat was slowly gnawing at the root and after sometime the root would break, and all would fall in the pit.

The sages said they were his ancestors. They would be relieved if Jaratkaru married and had a family. Only then they would salvation. They asked Jatarkaru to get married and then have a son who would be able to carry the line forward.

Jatarkaru said he had forsaken everything and was roaming around, naked. Who would agree to marry such a person.

He started roaming everywhere, this time in search of a wife. In the meantime, the spies of Vasuki, the serpent, told him that Jaratkaru was looking for a wife. Vasuki went to Jaratkaru and asked to marry his sister. His sister was called Jaratkri. Vasuki gave away his sister to Jaratkaru.
