Madhvaon Brahma Sūtra 4.1.16

Also Agnihotra, etc,, are useful for the enjoyment of enhanced heavenly bliss (as well as for the knowledge leading to release). The term ‘ ButJ shows that this is true only of the person who has seen Brahman, This is seen from the Sruti:—“ That Lord, if not known (seen), does not permit him (the ignorant) to enjoy bliss, just as the Vedas, (if) not duly studied under the preceptor, or duties, (if) not properly performed, are productive of no fruit; or even if he who does not know the Lord, performs any great meritorious deed, that indeed be- comes ultimately decayed ; therefore he should meditate on the Lord as the abode and guide; he who meditates on the Lord alone as his abode and guide has his works rendered undecaying, and by the grace of that Lord he creates for himself whatever he desires ” (Bri. III. 4- 15)-
