Bhāgavata Purāṇa
The Bhāgavata Purāṇa, universally known as the Śrīmad Bhāgavatam, is among the most celebrated granthams in all of Indian theological literature. Attributed to Vyāsa as his ultimate composition — the fruit of all his earlier work including the Mahābhārata and the other Purāṇas — it consists of twelve books (skandhas) containing approximately 18,000 verses. The Bhāgavata occupies a supreme place in Śrī Vaiṣṇava tradition as the Purāṇa that most completely expresses the nature of Bhagavān's personal accessibility to devotees, the sweetness (mādhurya) of His relationship with souls, and the doctrine of pure devotion (śuddha-bhakti).
The tenth skandha is the heart of the entire work and remains one of the most beloved texts in the bhakti tradition. It narrates Bhagavān Kṛṣṇa's birth in Mathurā, His childhood and youth in Vṛndāvana, the Rāsa Pañcādhyāyī (the five chapters of the divine dance), His slaying of Kaṃsa, and later episodes in Dvārakā. The eleventh skandha contains the Uddhava Gītā — Bhagavān's final instruction to His dear friend Uddhava before His departure from this world — which parallels and in some respects deepens the teaching of the Bhagavad Gītā. The twelfth skandha contains cosmological and eschatological material.
In Śrī Vaiṣṇava experience, the Bhāgavata is the Purāṇa-equivalent of the Divya Prabandham. The themes of Periyāzhvār's Tirumozhi — the childhood of Kṛṣṇa, the Mother Yaśodā's love — and Āṇḍāḷ's Tiruppāvai and Nāchiār Tirumozhi all resonate deeply with Bhāgavata narratives. Pillai Lokācārya's Mumukṣuppadi and Śrī Vachana Bhūṣaṇam draw on Bhāgavata verses to illustrate the primacy of Bhagavān's grace. Maṇavāḷa Māmunigaḷ's Upadēśa Rattiṉa Māḷai praises those who study both the Bhāgavata and the Nālāyira Divya Prabandham as possessing the fullest spiritual knowledge.
