Madhvaon Brahma Sūtra 4.1.12

Until release is obtained, meditation, etc., should be practised. For the Sruti says, “ O Venerable one, of . com these wise men, he who till he departs from this body con- stantly meditates on the Supreme declared by the sacred syllable,—what world does he attain to?” (Pr. v. i). The Sauparna Sruti says : “ Till release let him always meditate on Him (the Lord); for even the released meditate on Him.” The following is in the Brahmanda- purana s “ One should study scripture till ignorance is removed, should think till the doubt as to reasonable- ness is removed; meditation should continue till the perception of Brahman rises ; and the wisdom that has once dawned is never annulled. Even in the case of a person who has obtained wisdom, meditation is to be practised when his perception is interrupted. Likewise eternal and sincere devotion to the highest Brahman is necessary. This is followed as a rule of duty till entering into heaven; and it is practised thereafter by the released of their own accord.”
