|| अष्टमुखगण्डभेरुण्डनृसिंह स्तव: ||

The UpAsana of ashTa mukhagaNDabherunda narsimha is always passed down through secret small upAsaka groups ( mostly viravaishanavas ) so it is very difficult to find out any related stuff ins mantrashAtra compendiums. The texts related to ashTa mukhagaNDabherunda narsimha are almost kept hidden from adikshita folks and persons initiated in some other mantra. From fragments of such a text I’m posting “sharbha kruta ashTa mukhagaNDabherunda narsimha stava ” for common welfare of upAsakas & for preservation of such a very rare stuti of asThAsya gaNDabherunda swAmI .​
