per sthalapurana, the Saptarishis refused to receive dhan (alms)
from King Vrishadharbi, son of Sibi Chakravarthy as they thought
it was a sin to receive alms from the kings. The king tried to lure
them in many ways and subsequently arranged to kill them. The Lord
saved the rishis by killing kritiyai through Indra. The Saptarishis
proclaimed that Sriman Narayana is the Paradevata and the Lord took
the name Mayapiran at this place.
