十三、三學門。九、通三學以三學為義者，謂信等五喜樂捨。七、俱非緣亦爾者，謂七色根。一通三種、俱非緣者，是苦根，前據本性故言唯欲繫欲繫緣。今就三位故通三種緣，彼俱非以空無漏觀所引故言通也。憂非空觀引生，故不例。一、學俱非以三為義者，是憂根。

13. The section on the three trainings: Nine are open to the three trainings and have the three trainings as their object: namely, the five beginning with faith, joy, pleasure, and equanimity. Seven are neither, and their objects are likewise: namely, the seven physical faculties. One is open to the three kinds and takes neither as its object: this is the faculty of suffering. Previously, based on original nature, it was said to be bound only to desire and taking what is bound to desire as its object. Now, in terms of the three states, it is open to three kinds of objects; because it is induced by the contemplation of emptiness and taintlessness, it is said to be open to them. Grief is not induced by the contemplation of emptiness, so it is not analogous. One is in training and neither, having the three as its object: this is the grief faculty.
