सुरेष्वृषिष्वीश तथैव नृष्वपि

tiryakṣu yādaḥsv api te ’janasya
janmāsatāṁ durmada-nigrahāya
prabho vidhātaḥ sad-anugrahāya ca
O Lord, O supreme creator and master, You have no material birth, yet to defeat the false pride of the faithless demons and show mercy to Your saintly devotees, You take birth among the demigods, sages, human beings, animals and even the aquatics.
