The Tannisho: Lamenting the Deviations is a small book with an outsized heart. Written in the late thirteenth century by Yuien, a devoted disciple of the great Pure Land master Shinran, it preserves the master's most intimate teachings on faith, grace, and the boundless compassion of Amida Buddha. In plain, unadorned language, Shinran's words cut through centuries of religious complexity to a single, liberating truth: salvation is not earned but received. Yuien's own reflections, added after his master's death, warn against the many ways we distort that truth — through pride, through fear, through the endless busywork of self-improvement. This modern-English edition renders the Tannisho in clear, inviting prose that honors the original's directness and warmth. Whether you come to it as a student of Buddhism, a seeker, or a lover of timeless spiritual writing, this classic speaks with startling freshness to the questions we still carry.
