This paper aims to clarify the singularity of Other Power-shinjin 他力信心 in terms of the Cheng weishi lun. Prior studies point to the similarity of Other Power-shinjin and “Shōge 勝解 （*adhimukti, profound faith）.” But the sixth interpretation of deep mind 深心 by Shandao indicates that only the Buddha’s “wisdom 慧” can dispel “doubt 疑.” Therefore, those apart from the Buddha cannot establish profound faith. On the other hand, according to the fifth interpretation of “deep mind,” it can be acquired by being in accord with the Buddha’s words. This is because the essence of the deep mind is Śākyamuni’s “faith （xin 信）,” Buddhas’ faith which bears witness to the truth of his words, and Amida’s faith which motivates Śākyamuni and Buddhas. In view of the above, the singularity of Other Power-shinjin is in hearing the significance of the Name, putting aside an effort to dispel doubt by one’s own wisdom, being in accord with the significance of the Name, and thereby regarding the agent that gives rise to the shinjin as Amida.
