Question: "A layperson wishes to go forth, and a bhikṣu immediately receives him. Should he invite a master again or not? Is [the former] still the master or not?" Answer: "He is not the master. If one receives the Dharma from him, he may be the master; if one relies on and follows him, he may be the upādhyāya (master of reliance)."
