Within the Vaishnava vision, scripture is not merely a set of books but a many-layered revelation of Vishnu and his avatars. At the broadest level stand the Vedas and the Upanishads, received as foundational authority, with particular reverence for those portions and interpretations that affirm Vishnu or Narayana as the supreme reality. Closely allied to these are the Brahma Sutras, which systematize Upanishadic teaching and become a touchstone for later Vaishnava theologians. This Vedic and Vedantic core provides the metaphysical framework within which devotion (bhakti) to Vishnu is understood and practiced.

Flowing from this foundation are the great narrative and devotional texts that shape Vaishnava imagination and practice. The Bhagavad Gita, embedded in the Mahabharata, is central for all Vaishnava schools, presenting Krishna as the highest Lord and teaching devotion as the primary spiritual path. Alongside it stand the two epics, the Mahabharata and the Ramayana, especially the Valmiki Ramayana, which unfolds the life of Rama as an avatar of Vishnu. These epics are not only stories but living scriptures that instruct in dharma, devotion, and the nature of divine incarnation.

Among the Puranas, certain texts are especially cherished as distinctly Vaishnava. The Vishnu Purana and the Bhagavata Purana (Srimad Bhagavatam) hold a privileged place, narrating the deeds, qualities, and cosmic roles of Vishnu and his avatars, with the Bhagavata Purana in particular serving as a primary source for Krishna-centered devotion. Other Puranas such as the Padma Purana, Garuda Purana, Varaha Purana, Narada Purana, and Brahma Purana are also treated as important reservoirs of theology, cosmology, and devotional practice that consistently exalt Vishnu.

To guide concrete worship, temple ritual, and iconography, Vaishnavism turns to the Pancharatra and Vaikhanasa Agamas. These Agamic texts, including various Pancharatra Samhitas, lay down detailed procedures for consecration, daily worship, festivals, and the proper forms of divine images. In many Vaishnava communities, these ritual manuals stand alongside the Puranas and epics as practical scriptures, ensuring that devotion is expressed in a disciplined and traditional manner.

Finally, each major Vaishnava sampradaya receives and interprets this shared scriptural heritage through its own line of teachers and sacred compositions. Sri Vaishnavism treasures Ramanuja’s commentaries on the Brahma Sutras, the Bhagavad Gita, and the Upanishads, together with the Tamil hymns of the Alvars known as the Divya Prabandham. Madhva’s tradition, Gaudiya Vaishnavism, and other lineages similarly center on the Gita and the Bhagavata Purana, while also honoring the commentaries, treatises, and devotional works of their founding acharyas. In this way, a common scriptural core is refracted through multiple streams of interpretation, all converging on loving devotion to Vishnu and his incarnations.
