俱舍論疏 25.94

25.94

論「如是無間至非增上故」，明練根無間解脫唯用無漏道。《正理論》云「我所承稟諸大論師咸言：練根皆為遮遣見、修斷惑力所引發，無覆無記無知現行故。學位中修練根者，正為遮遣見惑所發。無學位中修練根者，正為遮遣修惑所發。如斷彼能發惑時，所起無間、解脫多少，如是如是斷彼所發無知現行道數亦爾。是故無學修練根時，用九無間、九解脫道。學位練根，二道各一。然見、修惑所發無智、隨所障殊有多品類。故轉退等成思等時、諸道現前各有所遣、由此無有超得勝性。」又云「以何等故名為練根？調練諸根令增長故。謂道力故令根相續，捨下得中、捨中得上，漸漸增勝名為練根。故練根名目轉根義。雖八解脫漸得勝根，而由本心求勝性故，未得勝性不捨前劣，如得後果方捨前向。若聖位中得勝種性，必捨前劣。煗等位中修練根者，但得勝性，劣性不行，名為轉根，非捨劣得。」

Regarding the treatise text “Thus the uninterrupted […] because it is not superior”: this clarifies that the uninterrupted and liberation paths of refining faculties use exclusively the undefiled path. The Nyāyānusāra says: “The great masters whose teachings I have received all said: The refining of faculties is entirely for the sake of eliminating the manifest activity of unobstructed neutral ignorance induced by the power of afflictions abandoned by seeing and cultivation. Those who cultivate refining of faculties in the stage of the trainee do so precisely to eliminate what is generated by afflictions of seeing. Those who cultivate refining of faculties in the stage of the non-trainee do so precisely to eliminate what is generated by afflictions of cultivation. Just as when abandoning the afflictions capable of generating them, there is a certain number of uninterrupted and liberation paths that arise, so too the number of paths that sever the manifest activity of ignorance generated by them is the same. Therefore, when the non-trainee cultivates refining of faculties, nine uninterrupted and nine liberation paths are used; for refining faculties in the stage of the trainee, the two paths are each one. However, the ignorance generated by the afflictions of seeing and cultivation has many varieties corresponding to the differences in what is obstructed. Therefore, when transforming [the lineage] liable to falling away and so on to accomplish [that of] deliberation and so on, each path that becomes manifest has that which it eliminates; because of this, there is no leaping over to attain a superior lineage.” It also says: “Why is it called refining the faculties? Because one tempers and refines the faculties to cause them to increase. That is, due to the power of the path, one causes the faculties in their continuum to abandon the inferior and attain the medium, to abandon the medium and attain the superior, gradually increasing in superiority, which is called refining the faculties. Therefore, the term ‘refining faculties’ designates the meaning of transforming faculties. Although through the eight liberations one gradually attains superior faculties, because one’s original aspiration seeks a superior lineage, before attaining the superior lineage one does not abandon the previous inferior [lineage], just as one abandons the previous approach only upon attaining the subsequent fruit. If one attains a superior lineage in the noble stage, one definitely abandons the previous inferior one. Those who cultivate refining of faculties in the stages of Warmth and the like merely attain the superior lineage without the inferior lineage operating, which is called transforming faculties, not abandoning the inferior to attain [the superior].”
