Madhvaon Brahma Sūtra 1.1.22

“ Who is the support of this world ? It is Akasa he) answered.” In this Chandogya text (I—9), Akasa appears to be the element ether. However, it (the element) cannot be (meant), but it is Vishnu only what is called Akasa; for the text declares attributes which belong only to Vishnu, viz., “ He is the Lord who is thrice supreme He is sung the supreme Lord; He is that which is unlimited.” (Ch. i: 9). Also compare the texts, “ Who could possibly tell the great (mighty) works of Vishnu ? Even the four-faced who tells the particles of dust cannot.’’ (Rv. 154. 1). “ Thou fillest all space with thy presence, and thou art past measuring.” (Rv. VII. 98.1). From these texts also that characteristic is appropriate to Vishnu alone. “ Vishnu alone is spoken of by the terms the unlimited, the glorious, Brahman (the perfect), the blissful and the like, which are applied to other in- dividuals only in a qualified sense” (the Brahma Parana). And it has been said, “ all names in their comprehensive sense declare Him (Vishnu).”
