sa bhavān sarva-lokasya bhavāya vibhavāya ca /
avatīrṇo 'ṃśa-bhāgena sāmprataṃ patir āśiṣām //

34. & 35. Thou whose Avataras in personalities, Thyself having no corporeal frame, art known by their supreme, matchless and unsurpassed powers which are not to be found in creatures conditioned by bodies,—such Thou, the Lord of all blessings, hast made this Avatar, with a ray of Thine, for the purpose of creation and protection of all the worlds.
