 The Pure Land path based on Amida is expounded in the Larger and Smaller Sutras of the Adornments of [the Buddha-field Named] Bliss (Sukhāvatīvyūha-sūtra), which trace their origins back to northwestern India in about the first century CE, the period of the redaction of the Prajñāpāramitā in 8000 Lines, Garland, Lotus, Vimalakīrti, and other major Mahayana sutras. These two sutras, along with the later Sutra of Contemplation on the Buddha of Immeasurable Life (Jp. Kanmuryōjukyō), form the foundation for the East Asian Pure Land tradition.
