SB 1.5 - The literatures of the paramahaṁsas
But literatures which describe the glories of the Lord are enjoyed by the paramahaṁsas who have grasped the essence of human activities. It may be said that none of the Purāṇas written by Vyāsa should be considered a place for crows, since nothing there is completely devoid of the glories of the Lord. But in SB 12.12.66 it is said that Nārāyaṇa is not glorified much in other works, but is abundantly and constantly described throughout the various narrations of Bhāgavatam. Thus we can understand that in other Purāṇas many of the stories are devoid of the glories of the Lord.
On the other hand, that literature which is full of descriptions of the glories of the name, fame, forms, pastimes, etc of the unlimited Supreme Lord is a different creation. These are full of transcendental words directed toward bringing about a revolution in the impious lives of this world’s misdirected civilization. Such transcendental literatures even though imperfectly composed are heard, sung and accepted by honest men. These literatures are sometimes composed strictly and sometimes carelessly, but with sparse ornaments in the verses contain names and descriptions of the Lord’s glories. The devotees hear, and having heard, sing, and having sung, again hear, since they are not satiated. If a speaker is present, they hear the glories. If a hearer is present they speak the glories. Otherwise, they spontaneously sing the glories.
