Madhvaon Brahma Sūtra 4.1.5

In the Supreme Lord, the notion of perfectness should by every means; be secured; for it is the most exalted attribute and the contemplation becomes thereby exalted. The following is said in the Brahma Tarka: “ Certainly by all Vishnu is to be ever contemplated as Brahman (with' the idea that He is perfect); for the word Brahman means ‘ greater or perfect His knowledge and meditation consist in knowing and thinking Him to be great; and of all things, only such knowledge and medita- tion would highly please the Lord. Hence that should by all means be secured. Whenever Atman is contem- plated as the Lord, the attribute Brahman (the perfect) should be added to Atman; and on no account the attri- bute of perfectness should be omitted in the contempla- tion of Vishnu.”
