七失師法，列示中，初明和尚無失。無德依他者，但可捨去，相依仍在。以下，示無失所以。初受期心，盡壽親附；不同依止，容有再請故也。二明依止有失。若論依止，但有請法；義分三種，故云詳正。若失請法，則須重加；若失下二，起心而已，如後所明。

Seventh, on the loss of a master: in the list and explanation, first, explaining that the upādhyāya is not lost. "Lacking virtue and relying on another" means one can only depart from him, but the mutual dependence remains. From "Because" downward, showing the reason why he is not lost. The initial intention upon receiving ordination is to attend closely upon him for the rest of one's life; it is unlike the niśraya-master, where there is room to make a request again. Second, explaining that the niśraya-master can be lost. In discussing the niśraya, there is only the requesting dharma; in principle it divides into three types, hence it says "examine and rectify." If one loses the requesting dharma, one must repeat it; if one loses the lower two, it is merely generating a thought, as explained later.
