大乘義章 20.38

20.38

第二定體。於中曲有五門分別：一總定體、第二約就五眼分別、第三約就七通分別、第四約就十一智分別、第五約就四念分別。初總定體。人說不同，如《地持》辨。有人宣說：信等五根為力體性。有人宣說：智慧為體。《地持》所存，智慧為體。故彼文言「經說處非處智力，不說處非處信等力。」如是一切，明知十力用智為體，非是信等。總定如是（此一門竟）。

Second, determining the essential nature. Within this, there are five subdivisions: 1. Determining the essential nature in general; 2. Distinguishing them according to the five eyes; 3. Distinguishing them according to the seven abhijñās; 4. Distinguishing them according to the eleven knowledges; 5. Distinguishing them according to the four applications of mindfulness.
First, determining the essential nature in general. People's explanations differ, as distinguished in the Bodhisattvabhūmi. Some state: the five faculties such as faith constitute the essential nature of the powers. Some state: prajñā constitutes their essential nature. What is maintained in the Bodhisattvabhūmi is that prajñā constitutes their essential nature. Hence that text says: 'The sūtras speak of the power of knowledge of what is possible and impossible; they do not speak of the power of faith and so forth regarding what is possible and impossible.' And so on for all of them; thus we know that the ten powers take knowledge as their essential nature, not faith and the rest. Such is the general determination (this concludes section one).
