In the Mahabharata Anusashana Parva there is an anecdote of the Saptarshis encountering the Yatudhani named Krtya (an asura) with an intention of killing them but first asking them to explain the meaning of their names. Sri. Nityananda Mishra has put together this anecdote and explains how the Saptarshi explain their names along with their esoteric meanings. The Saptarshi's seeking to pick the lotuses from the lake guarded by Yatudhani are allowed to do so only after explaining their names. The rshis sense the motive of Yatudhani and explain their names in an esoteric manner not understandable to the asura.
