25.14

釋曰：有學與異生種姓皆有六，以應果六種。因有學異生種姓有六，故無學中有六種也。然於見道必無練根，以見道速疾，無容起彼練根加行故。

Explanation: Both trainees and ordinary persons have six lineages, corresponding to the six kinds of worthy ones' fruits. Because trainees and ordinary persons have six lineages as causes, there are six kinds in no-learning. However, there is definitely no honing of faculties on the path of seeing, because the path of seeing is swift and does not admit the preparatory application of honing the faculties.
