13.64

The explanation says: "Avijñapti is declared; the remaining three [exist in all]" is the differentiation of the three moral natures. That is, avijñapti-rūpa does not extend to the indeterminate; it is only wholesome or unwholesome in nature, hence it is said to be "declared" (vyākṛta). "The remaining" refers to vijñapti karma and mental volition, which both extend to all three moral natures. Question: "Why does avijñapti not extend to the indeterminate?" Answer: "Because the strength of an indeterminate mind is weak and feeble, it cannot initiate strong avijñapti karma such that when the cause has ceased, the fruit still continues to arise; therefore avijñapti karma is not indeterminate."
