SB 1.2 - The way to recite Bhāgavatam
Before reciting Bhāgavatam, which is the very means of conquest, one should offer obeisances unto the Personality of Godhead, Nārāyaṇa, unto Nara-Nārāyaṇa Ṛṣi, unto Sarasvatī and unto Vyāsadeva, the author. Nara-Nārāyaṇa spoke Bhāgavatam to Nārada, who then repeated it to Vyāsa. Vyāsa later spoke it to Sarasvatī. Nara-Nārāyaṇa are also the presiding deities of the place, Badarikāśrama, where Vyāsa first wrote the Bhāgavatam. Sarasvatī is the śakti of the work. This is not the material deity but the spiritual counterpart, who gave Kṛṣṇa mantra to Brahmā in Brahma-Saṁhitā.
The living being cannot get out of the material existence by making plans. If he wants to conquer his perpetual struggle for existence, he must reestablish his relation with God. And thus one should take shelter of the Vedas and the Purāṇas, which are the supplementary explanations of the Vedas. Different men are conducted by different modes of nature, and the Purāṇas are so divided that any class of men can take advantage of them and get out of the hard struggle for existence. Śrīmad Bhāgavatam is the spotless Purāṇa meant for those who desire to get out of material entanglement permanently.
