第二無漏色證者，如契經說：「無漏法云何？謂於過去、未來、現在諸所有色不起愛恚，乃至識亦然，是名無漏法。」此經既言有無漏色，明知無表體必實有。除無表外，更無有色名無漏也。

Second, as for the proof from untainted forms: as a sūtra states, "What are untainted phenomena? Namely, when neither craving nor anger arises toward any forms of the past, future, or present, and so forth up to consciousness as well; these are called untainted phenomena." Since this sūtra speaks of untainted forms, one clearly knows that the substance of avijñapti must be real. Aside from avijñapti, there are no other forms that are called untainted.
