Translation: 
Śrīmad-Bhāgavatam is the spotless Purāṇa. It is most dear to the Vaiṣṇavas because it describes the pure and supreme knowledge of the paramahaṁsas. This Bhāgavatam reveals the means for becoming free from all material work, together with the processes of transcendental knowledge, renunciation and devotion. Anyone who seriously tries to understand Śrīmad-Bhāgavatam, who properly hears and chants it with devotion, becomes completely liberated.
Purport: 

Because Śrīmad-Bhāgavatam is completely free of contamination by the modes of nature, it is endowed with extraordinary spiritual beauty and is therefore dear to the pure devotees of the Lord. The word pāramahaṁsyam indicates that even completely liberated souls are eager to hear and narrate Śrīmad-Bhāgavatam. Those who are trying to be liberated should faithfully serve this literature by hearing and reciting it with faith and devotion.
