Sūtra translation
The attributes are to be comprehended from all the Vidyas because even in Purusha-Vidya, (while some only an mentioned), some others are not.
For even in the Vidya or knowledge conveyed by the Purusha Sukta (which is considered the highest of all the Vidyas), some of the qualities required to be known by the eligible are not declared. The Brahma Tarka says: “ Throughout the Purusha Sukta, the qualities of Vishnu are declared more than in any other j even there all the qualities are not exhaustively des- cribed ; hence they are to be comprehended from a study of all Scripture.”
