sincere mind　至心 The term appears in the Eighteenth Vow of the Larger Sutra, and it is identical with the first of the three minds enumerated in the Contemplation Sutra: sincere or genuine mind, deep mind, and desire for birth. In the Pure Land tradition, sincere mind meant the uncontrived, open sincerity of the believer, but Shinran realized that in the depth of each person such a mind is impossible and that true sincerity is Amida’s sincere mind actively working in the mind and heart of defiled persons and enabling them to entrust themselves to Amida. This mind that has entrusted itself to Amida―in other words, the mind grasped by Amida―is sincere mind. Hence sincere mind is a synonym for entrusting (shingyō). In Shinran’s interpretation, sincere mind refers to the mind of Buddha and not that of practicers, but since the Buddha-mind is great compassion, it fully realizes itself only in becoming one with the foolish mind of human beings. The direct meaning of entrusting is the mind of a person that realizes shinjin and is joyful in that realization, but since this entrusting is Other Power giving itself to one, it also has the mind of Buddha as its fundamental nature.
