佛祖統紀 29.5

29.5

直指人心見性成佛。至矣哉。斯吾宗觀心之妙旨也。謂之教外別傳者。豈果外此為教哉。誠由此道以心為宗離言說相故。強為此方便之談耳。不然何以出示楞伽令覽教照心耶。何以言大乘入道藉教悟宗耶。為同此宗撰達磨禪宗志（覽教照心見本志。藉教悟宗見達磨入道四行）。

Directly pointing to the human mind, seeing one's nature and attaining Buddhahood—how supreme! This is the subtle purport of contemplating the mind in our own tradition. As for calling it "a special transmission outside the teachings," could it truly be outside of these teachings? It is truly because this path takes the mind as its principle and is free from the marks of verbal explanation that it is forcibly given this expedient expression. Otherwise, why would [Bodhidharma] present the Laṅkāvatāra Sūtra to make people inspect the teaching and illuminate their minds? Why would it be said that "entering the path through the Great Vehicle relies on the teachings to awaken to the principle"? For the sake of this common principle, I have composed the "Treatise on the Bodhidharma Chan Tradition" (inspecting the teaching and illuminating the mind appears in this treatise; relying on the teachings to awaken to the principle appears in Bodhidharma's Four Practices for Entering the Path).
