Within Jōdo-shū, the heart of the tradition is anchored in what are known as the Three Pure Land Sutras (Jōdo Sanbukkyō). These are the Larger Sukhāvatīvyūha Sūtra (Muryōju-kyō), the Smaller Sukhāvatīvyūha Sūtra (Amida-kyō), and the Amitāyurdhyāna Sūtra (Kanmuryōju-kyō). Together they set forth Amitabha Buddha’s vows, the nature and splendor of the Western Pure Land, and the centrality of nenbutsu—the recitation of the Buddha’s name—as the decisive practice. They also describe graded paths of rebirth and contemplative methods, showing how beings of differing capacities can be guided toward Amitabha’s realm. In this way, the scriptural core of Jōdo-shū is not merely doctrinal, but deeply practical, shaping how faith and practice are actually lived.

Alongside these sutras, Jōdo-shū takes as foundational a set of influential commentaries that interpret and systematize Pure Land teaching. Works such as Tanluan’s Ōjō-ron-chū, Daochuo’s Anraku-shū, and Shandao’s Kangyō-sho explore the meaning of the Pure Land path, emphasizing reliance on Amitabha’s vow and clarifying the role of exclusive nenbutsu. These commentaries serve as bridges between the sutras and the lived religious life of practitioners, drawing out implications that might otherwise remain implicit. They help articulate why entrusting oneself to Amitabha and reciting the nenbutsu is regarded as a complete path, even for those who feel spiritually limited or burdened by karmic obstacles.

Finally, the writings of Hōnen, especially the Senchaku Hongan Nenbutsu-shū, crystallize these scriptural and commentarial streams into a distinctly Jōdo-shū vision. By presenting nenbutsu as the selected practice grounded in Amitabha’s original vow, Hōnen’s work gives Jōdo-shū its characteristic emphasis on faith-based recitation as the primary means to birth in the Pure Land. In this constellation of texts—the Three Pure Land Sutras, the classical commentaries, and Hōnen’s own treatise—the tradition finds both its doctrinal backbone and its devotional heart. For the earnest seeker, these writings function not only as objects of study, but as guides that continually point consciousness toward Amitabha’s compassionate promise.
