[Shinran, the founder of the Jōdo-Shin or True Pure Land sect, put absolute stress on the idea of “other-power.”]

Shinran’s emphasis tariki [other-power] even extended to the nembutsu itself. Honen had stressed repeated recitation of the nembutsu to purify oneself of evil karma and to assure one’s rebirth. He himself appears to have chanted sixty thousand, and later seventy thousand, nembutsu a day. Shinran, on the other hand, felt that excessive preoccupation with the number of recitations placed too much emphasis on one’s own endeavors. A single nembutsu uttered with faith would ensure one’s rebirth; subsequent callings-on-the-name were meaningful as expressions of gratitude. …

What evolved [from Shinran’s teaching] differed not only from Honen’s doctrine but virtually from the whole of Buddhism: a teaching in which the principles of karmic causality and merit accumulation, as well as aspiration and endeavor for enlightenment, were in effect set aside and superseded by faith in the original vow. And even the fact that one had faith, Shinran held, was not due to one’s own will to believe, but to one’s being grasped (seshu) by Amida’s compassion.
