Before reciting this Śrīmad-Bhāgavatam, which is the very means of conquest, one should offer respectful obeisances unto the Personality of Godhead, Nārāyaṇa, unto Nara-nārāyaṇa Ṛṣi, the supermost human being, unto mother Sarasvatī, the goddess of learning, and unto Śrīla Vyāsadeva, the author.
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
नारायणं नमस्कृत्य नरं चैव नरोत्तमम् । देवीं सरस्वतीं व्यासं ततो जयमुदीरयेत्
nārāyaṇaṃ namaskṛtya naraṃ caiva narottamam | devīṃ sarasvatīṃ vyāsaṃ tato jayamudīrayet
