下釋所以，以末那共唯種子所引故任運恒生。言非所對治至差別轉故者，明末那識不同所治六識，要待根境作意緣力方生，亦不同彼能治聖道要待見真如境解力方起，由此道理世間治道若起不起此惑恒行。

Below, explaining the reason: because manas is commonly induced solely by seeds, it arises constantly and spontaneously. Regarding the statement, "Because it is not that which is counteracted […] operates differently": this clarifies that the manas consciousness is not like the six consciousnesses that are to be counteracted, which require the conditional force of faculties, objects, and attention to arise; nor is it like the noble path that acts as the antidote, which requires the power of understanding that sees the realm of tathatā to arise. By this principle, whether the worldly path of antidotes arises or does not arise, this affliction operates constantly.
