Shinran's late letters compiled by disciples

Mattōshō ('Lamp for the Latter Ages,' compiled posthumously, originating in letters from Shinran's last decades c. 1250-62) is the major collection of Shinran's (1173-1263) late pastoral letters, compiled and arranged by his disciples — principally his grandson Renkū and great-grandson Kakunyo and the Honganji-line successors — into a 23-letter epistolary corpus that became fundamental to Jōdo-Shinshū doctrinal-spiritual formation. Shinran wrote these letters from his last years in Kyoto, after his return from the long Kantō missionary period (c. 1207-35) where he had founded the rural-east-Japanese Pure-Land communities. The letters address: (1) doctrinal questions from confused or quarrelling Kantō followers about the meaning of shinjin (the entrusting heart, the central Shinshū category for the believer's faith-as-gift); (2) practical-pastoral counsel about anti-nembutsu persecution by other Buddhist schools; (3) the relation between Shinran's teaching and Hōnen's; (4) the proper handling of disagreements among Shinran's own followers (including the painful disowning of his son Zenran for heretical claims to private teaching); (5) the role of the nembutsu, the assurance of birth in the Pure Land, the role of gratitude (hōon). The letters are written in vernacular Japanese rather than Kanbun, making them accessible to lay followers without classical training, and exemplify the Shinshū pastoral-democratic ethos. The collection has functioned as one of the principal pastoral-doctrinal resources of Jōdo-Shinshū across the Hongan-ji and Ōtani lineages from medieval through modern Japan and the contemporary diaspora.
