注大乘入楞伽經 2.188

2.188

言但住心量觀察三有，又云令達唯心漸入諸地者，謂此一心法門，是凡聖之本，迷之墮世間生死、悟之證出世菩提。故先聖曰「世間不越三科，出世不過二果。」二果者，即如上釋成如來身二轉依果也。三科者，即此五蘊、十二處、十八界，諸妄心法也。故云欲得佛身，應當遠離，乃至觀察令達唯心。於自心宗勸善修學。

Saying "only abiding in cittamatra, contemplating the three realms of existence," and also "causing them to realize mind-only and gradually enter the stages" means: this Dharma door of the one mind is the root of both ordinary beings and sages; deluded about it, one falls into worldly saṃsāra; awakened to it, one realizes supramundane bodhi. Therefore the ancient sages said: 'The mundane does not exceed the three categories; the supramundane does not surpass the two fruits.' The 'two fruits' are the two fruits of the transformation of the basis that accomplish the Tathāgata's body, as explained above. The 'three categories' are these five skandhas, twelve āyatanas, and eighteen dhātus—all dharmas of the deluded mind. Hence it says: if one wishes to obtain the Buddha's body, one should stay far away from them, and contemplate so as to realize mind-only. It encourages skillful study and practice toward the tenet of one's own mind.
