四破內外者。律因裸形外道與舍利弗論義，便謂沙門釋子智慧聰明；後見跋難陀，即從出家；問跋難陀義而不能答，彼即休道；比丘白佛，佛言：自今已去，聽與外道四月共住，白二羯磨；先與剃髮受十戒，後作羯磨。（此制試初來外道非破內外者。）後又有一外道纔四月試，即得正信；佛令便與受具，前裸形聞已，復來出家；佛言：此壞內外道者，於我法中，無所長益，從此制斷。所言破者，邪正兩見俱壞故；《疏》云：正取破內，兼實破外是也。

Fourth, "destroying the internal and external": In the Vinaya, because a naked ascetic debated with Śāriputra and thought that the Śākyan recluses possessed wisdom and intelligence, he later saw Upananda and went forth under him. When he asked Upananda about doctrinal meanings, the latter could not answer, so he abandoned the path. The bhikṣus reported this to the Buddha, and the Buddha said: "From this day forward, I permit giving non-Buddhists four months of living together with a jñaptidvitīyā karmavācanā; first have him shave his hair and receive the ten precepts, and afterward perform the karma." (This regulation tests non-Buddhists who come for the first time, not those who destroy the internal and external.) Later, another non-Buddhist, after only four months of testing, attained right faith; the Buddha instructed that he be granted the complete precepts at once. When the former naked ascetic heard this, he came back to go forth. The Buddha said: "This person who destroys both internal and external paths brings no growth or benefit in my Dharma"; from then on, he instituted the prohibition against it. What is called "destroying" is because both wrong and right views are corrupted. As the *Commentary* says: "It primarily takes destroying the internal, and also genuinely takes destroying the external"; this is it.
