仁王般若經疏 3.71

3.71

「是不定人是定人者，入生空位聖人性故，必不起五逆、六重、二十八輕，佛法經書作反逆罪言非佛說，無有是處。能以一阿僧祇劫修伏道忍行，始得入僧伽陀位。」

"These indefinite persons become definite persons because they enter the stage of the emptiness of living beings and possess the nature of noble persons; they will certainly not commit the five heinous crimes, the six grave [offenses], or the twenty-eight light [offenses]; that they would commit rebellious crimes against the Buddhist scriptures and teachings, claiming they are not what the Buddha spoke, is impossible. Being able to cultivate the practice of the patience of the path of subjugation for one asaṃkhyeya kalpa, they first manage to enter the stage of saṃghāta."
