入楞伽心玄義 1.43

1.43

四、顯德者，謂一心真性周絕四句、逈超情表，猶崖城絕戶，故云難入。垂言巧辨宣示悟入，故云能入。此即教入義而義現也。

Fourth, concerning revealing the virtue, the true nature of the one mind completely transcends the four alternatives and vastly surpasses the realm of conceptual feeling, just as the cliff-top city lacks gates; hence it is said to be difficult to enter. Manifesting speech and skillful eloquence to preach and reveal awakening and entering; hence it is said to be able to enter. This means that the teaching enters the meaning and the meaning is revealed.
