楞伽阿跋多羅寶經註解 3.108

3.108

此三種智約一人所知而言，據後偈文，即如來所知之三也。知生滅者，一切智也；知自共相者，道種智也；知不生不滅者，一切種智也。只一佛智而有三用，名為三智。又云無礙相是智者，謂於前之三智一心融泯，無染礙之相是智，反是則為識也。又云三事等者，三事即根、塵及我，三事和合相應而生是識，此不知自性相故。若知性相，則一念靈知不假緣生，故曰「無事方便自性相是智」也。又云得相不得相為識智者，相即性相之相，相惟是一，而有離不離之異，故云得不得也。自得者，所謂如來自得聖智境界，無以名狀，故云「不出不入如水中月」也。

These three kinds of knowledge are spoken in terms of what one person knows; according to the subsequent verses, they are the three known by the Tathāgata. Knowing arising and ceasing is the knowledge of all phenomena (sarvajñatā); knowing particular and common characteristics is the knowledge of the aspects of the path (mārgākārajñatā); knowing neither arising nor ceasing is the knowledge of all aspects (sarvākārajñatā). There is only one Buddha-knowledge, yet it has three functions, which are called the three knowledges. Furthermore, saying that "unhindered characteristics are knowledge" means that when the former three knowledges are fused and eliminated in one mind, characteristics free of defilement and hindrance are knowledge; the opposite is consciousness. Furthermore, saying "the three factors, etc." refers to the sense faculties, sense objects, and the self: when the three factors combine and arise in correspondence, this is consciousness, because it does not know the nature-characteristic. If one knows the nature-characteristic, then a single thought of numinous awareness does not depend on conditions to arise; hence it is said, "The characteristic of the nature devoid of expedient means in things is knowledge." Furthermore, saying that "grasping characteristics and not grasping characteristics are consciousness and knowledge": "characteristics" refers to the characteristics of the nature and characteristics; the characteristic is only one, yet there is the difference of being detached or not detached, and therefore it is spoken of as grasping or not grasping. "Attaining it by oneself" refers to the realm of the Tathāgata's own attainment of noble knowledge, which cannot be named or depicted; thus it is said, "It neither goes out nor enters, like the moon in the water."
