楞伽阿跋多羅寶經註解 3.61

3.61

欲善化導，必宗說俱通，方能誘物而底于道。蓋宗者道之本，說者教之跡。宗以明趣，趣不明則失其所歸；教以詮理，理或昧則迷其所入。故宗通而說不通，理雖精而不顯；說通而宗不通，言雖辯而非要。而二者實相須為用，不可偏廢也。大慧請說宗通相而不及說者，舉其要耳，宗通則說在其中矣。答中兼言者，必二而後備也。

To skillfully transform and guide, one must penetrate both the doctrine and the teaching; only then can one induce beings and lead them to the Way. For the doctrine is the root of the Way, while the teaching is the trace of instruction. The doctrine clarifies the purpose; if the purpose is not clear, one loses where to return. The teaching explains the principle; if the principle is obscured, one is lost as to where to enter. Therefore, if one penetrates the doctrine but does not penetrate the teaching, although the principle is refined it is not revealed; if one penetrates the teaching but does not penetrate the doctrine, although words are eloquent they lack the essential. Thus the two truly require each other to function and cannot be one-sidedly neglected. Mahāmati requested the explanation of the characteristic of penetration of the doctrine without mentioning the teaching merely because he brought up the essential; if the doctrine is penetrated, the teaching is contained within it. That the Buddha mentions both in his reply is because both must be present to be complete.
