起信論疏筆削記 4.19

4.19

疏　世者下，三、明佛口業，中三：今初、所救。三世間者，智正覺世間、眾生世間、器世間。正覺為能化，眾生為所化，器界為化處。以器界是無情，正覺是佛，故唯眾生為所救也。

In the Commentary, from "the world" downward, third, clarifying the Buddha's vocal action, which has three parts; this is the first: that which is rescued. The three realms are: the realm of enlightened cognition, the realm of sentient beings, and the realm of the vessel. Enlightened cognition is that which transforms; sentient beings are that which is transformed; the vessel realm is the place of transformation. Because the vessel realm is insentient and enlightened cognition is the Buddha, only sentient beings are that which is rescued.
