大方廣佛華嚴經隨疏演義鈔 43.50

43.50

疏「今以智覺察」者，下示不為癡亂所以。「如人覺賊及偷狗」者，即《涅槃南經．邪正品》，北經亦〈如來性品〉即第七經，如人覺賊，賊無能為。又因迦葉問依四種人。難云：「世尊！魔等尚能變作佛身，況當不能作羅漢等？」佛言：「善男子！於我所說若生疑者，尚不應受，況如是等。是故應當善分別知。善男子！譬如偷狗，夜入人舍。其家婢使若覺知者，即應驅罵：『汝疾出去。若不出者，當奪汝命。』偷狗聞之，即去不還。汝等從今亦應如是降伏波旬，應作是言：『波旬！汝今不應作如是像。若故作者，當以五繫繫縛於汝。』魔聞是已，便當還去。如彼偷狗，更不復還。」下乃廣說佛說魔說之相。此文但令覺察。

Regarding the Commentary's line "Now, using wisdom to perceive and discern": below, it shows the reason why he is not deluded or confused. "Like a person who perceives a thief or a thieving dog" comes from the "Chapter on Heterodoxy and Orthodoxy" in the Southern Recension of the Nirvāṇa-sūtra—in the Northern Recension, it is also the "Chapter on the Tathāgata Nature," that is, the seventh fascicle: just as when a person perceives a thief, the thief can do nothing. Further, it is based on Kāśyapa's question about relying on four kinds of persons. He objected, saying: "World-Honoured One! If māras and their kind can even transform themselves into the body of a Buddha, how much more can they not produce the form of an arhat and so on?" The Buddha said: "Good son! If you give rise to doubt about what I have preached, you should not even accept it, how much less such as these. Therefore, you should skillfully distinguish and know. Good son! For example, take a thieving dog entering a person's house at night. If the household's servant maids detect it, they immediately drive it away and scold it: 'Get out quickly! If you do not get out, I will take your life.' When the thieving dog hears this, it immediately leaves and does not return. From now on, you all should also subdue Pāpīyān like this. You should speak these words: 'Pāpīyān! You should not now create such an appearance. If you deliberately do so, I will bind you with the five bonds.' When Māra hears this, he will then turn back and leave. Like that thieving dog, he will never return again." Below, it then expounds at length the marks of what the Buddha preaches and what Māra preaches. This text merely enjoins perceiving and discerning.
