24.107

「既通由二至同所作故」者，此即第二道引離繫得。如文可知。又《顯宗》三十二云「由此有學離八修斷，世、出世道隨一現前，各未來修世、出世道。此總相說，以無漏道離上七地前八品時，不修上邊世俗道故，唯有無漏一離繫得，離第九品方可具二。或應許得離繫道而修，或應斷染時許依下修上。

[On the text,] "Since it is accomplished through both [...] because they have the same function": This is the second: the path induces the attainment of disjunction. It is understandable from the text. Furthermore, the Xianzong lun, fascicle 32, states: "Hence, when a trainee detaches from the eight [stages] to be abandoned by cultivation, whichever one of the mundane or supramundane paths manifests, both cultivate the mundane and supramundane paths in the future. This is a general statement, because when one detaches from the first eight grades of the upper seven stages via an anāsrava path, one does not cultivate the conventional path of the higher limits, and thus there is only a single anāsrava attainment of disjunction; only when detaching from the ninth grade can one possess both. Alternatively, it should be accepted that one cultivates the path while obtaining disjunction, or that when severing defilement, one cultivates the higher based on the lower."
