Nanga Baigin nails down the earth

A Baiga telling written down by Verrier Elwin explains the tribe's bond with the ground. When the earth was first made it would not stay in place; it slipped about like mud. Bhagavan, the high god, called for Nanga Baiga. He and his wife Nanga Baigin, the first of the Baigas, had come into being from drops of the sage Vashishta's urine, and they are spoken of as the Baiga Adam and Eve. It was the wife who did the work: she hammered nails into the four corners of the world and the earth became firm. The Baigas take from this their standing as guardians of the earth, which is why they traditionally refused to break it with a plough. No Shiva or Vishnu takes part.
