Madhvaon Brahma Sūtra 1.3.43

“ He is the Supreme Lord of all. He is the Lord of the lords that rule the world. He indeed is this (Samana) but unlike what is seen, what is heard, etc.” (Bri. VI. iv) 22). From the appellations, “ the Supreme Lord,” &c. occurring in these and similar texts, the eternally glorious is Vishnu only. “ Also He is the ruler of the released for He surpasses the beings of this world ” (T, A. III. 12). “ The seven who are endowed with the power of the glorious and worshipful Lord stand appointed in their (posts of) various duties, by the command of Vishnu—the seven in whom the world lies latent” (Rv. 1.164. 36). “ He who is everywhere, but not heard, etc.” (A. A. III. ii. 4). From these texts, it is plain, all these terms (of course) belong to Vishnu only.
