threefold shinjin　三信;三心 The threefold shinjin contained in the Eighteenth Vow are 1) sincere mind, 2) trust and 3) aspiration for birth in the Pure Land, each of which, according to Shinran, is completely free of doubt, including self-will, calculation, and self-power. Hōnen identified them with the three minds of the Contemplation Sutra as necessary mental attitudes of the nembutsu practicer. Shinran, however, regarded them as the manifestations of the working of Other Power, stating that the sincere mind of the Buddha enters the ignorant and deluded mind of persons, causing in them the experience of joyful faith and prompting them to aspire for the Pure Lad. He also summarized the threefold shinjin into the mind that is single, which is none other than the Other Power. Thus, the threefold shinjin can be seen as the true and real mind of the Buddhas its manifestation in the heart and mind of the person of shinjin.
