3.121

From "no self..." downward, it explains the reason for forbearance. This has two senses, namely general and specific. Generally, because of the absence of the mark of a self, even when repeatedly subjected to dismemberment, one can always endure it. Specifically, it is because there is no self that one can endure, and it is on account of repeated suffering that one can endure.
