And he came finally to be known by the name of Kalmāşapāda.* And from him sprung Śarkhana. And Sudarśana was Sankhana's and Agnivarna was Sudaśana's son. He incurred Vasiştha's curse, and was turned into a Rākşasa. He took up water, intending to clear scores with Vasistha; but at the request of his wife, desisted, pouring down the water at his own feet. Hence the name of Kalmāşapāda.
कल्माषपादोऽप्यभवत् तस्माज्जातस्तु शङ्खणः। सुदर्शनः शङ्खणस्य अग्निवर्णः सुदर्शनात्॥
