注大乘入楞伽經 7.36

7.36

This says that because they falsely conceptualize and give rise to attachment to un real, diverse external phenomena, failing to understand that all are the direct perception of their own minds, they cannot know that which is not a worldly treatise. The Treatise on the Awakening of Faith says: "All phenomena have distinctions solely based on false thoughts; if one is free from mental thoughts, there are no characteristics of any external sphere. Therefore, from the beginning, all phenomena are free from the characteristics of verbal expression, free from the characteristics of names, and free from the characteristics of mental conditioning; they are ultimately equal, without alteration, and indestructible. Because they are only the one mind (ekacitta), they are called suchness (tathatā)." Being able to dwell in one's own sphere, not giving rise to false mental discriminations of existence and non-existence—this is the Tathāgata's Dharma, not what is possessed by the heterodox.
