Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
भूरीणि भूरिकर्माणि श्रोतव्यानि विभागशः । अतः साधोऽत्र यत्सारं समुद्धृत्य मनीषया । ब्रूहि नः श्रद्दधानानां येनात्मा सम्प्रसीदति
bhūrīṇi bhūrikarmāṇi śrotavyāni vibhāgaśaḥ | ataḥ sādho'tra yatsāraṃ samuddhṛtya manīṣayā | brūhi naḥ śraddadhānānāṃ yenātmā samprasīdati
