26.116

釋曰：練根無間道，學六無學七者，有學練根諸無間道未來修六，謂四諦智、法智、類智。無學練根諸無間道未來修七智，於前六上更加盡智。

The explanation says: [Regarding] "In the uninterrupted path of training the faculties, a śaikṣa [cultivates] six, an aśaikṣa seven": in the various uninterrupted paths of training the faculties, a śaikṣa cultivates six in the future, namely the knowledges of the four truths, dharma-knowledge, and category-knowledge. In the various uninterrupted paths of training the faculties, an aśaikṣa cultivates seven knowledges in the future, adding the knowledge of exhaustion to the previous six.
