Srimad Bhagvata Mahapurana: Book 7: Chapter 6: Verses 25-30
Prahrada's teaching to the demon boys
When that infinite Being, the Cause of all, is pleased, what is there that cannot be attained? And what is the use of our worrying over religious merit etc., which are attained in this world of their own accord (without any effort) through modification of the three Gunas (in the form of destiny moulded by one's past actions); and what is the use of hankering after final beatitude (which lies beyond the three Gunas) to us who enjoy the nectar of His (lotus) feet and are (ever) singing His praises? The triad which has been spoken of (in the Vedas) as the three objects of human pursuit-viz., religious merit, worldly riches and sensuous enjoyment-as well as the science of Self-Realization, the science of rituals, logic and political science and the diverse means of earning one's livelihood-all this subject-matter of the Veda I regard as true, (only) if it enables one to offer one's self to the supreme Person, one's Inner Controller.
(The divine sage) Narayana, the (eternal) Companion (and Brother) of (the sage) Nara (His divine Counterpart), it is said, taught this well-known and pure wisdom-which cannot be easily attained-to (the sage) Narada. It can (however) be (easily) attained by (all) embodied beings who have bathed themselves in the dust of the lotus-feet of those exclusively devoted to the Lord, and claiming nothing as their own. This knowledge with the immediate apprehension of truth as well as the pure (innocent) cult of Devotion to the Lord was received by me in the past through hearing from the mouth of the sage Narada, who has seen the Lord (with his own eyes). The sons of the Daityas said: Prahrada, you as well as we know no other teacher except these two sons of Sukra (the preceptor of the Daityas) and indeed these two have been our masters ever since we were mere infants. (And) association with an exalted soul (like Narada) was (most) difficult when you were an infant (shut up) within (the four walls of) the gynaeceum. Resolve our doubt, O gentle one, if there is any (valid) ground for giving credence to your words.
Thus ends the sixth discourse, forming part of the Narrative of Prahrada
in Book Seven of the great and glorious Bhagavata-Purana,
otherwise known as the Paramahamsa-Samhita.
