摩訶止觀 2.139

2.139

當知種種相、種種說、種種神力，一一皆入祕密藏中。何等是旨歸？旨歸何處？誰是旨歸？言語道斷，心行處滅，永寂如空，是名「旨歸」。至第十重中，當廣說也。

One should know that all kinds of marks, all kinds of teachings, and all kinds of spiritual powers each and every one enter into the secret storehouse. What is the ultimate import? To what place does it return? What constitutes the ultimate import? The path of words is cut off, the place of the mind's activity is extinguished, and it is eternally quiescent like space: this is called the 'ultimate import'. When we come to the tenth section, it shall be explained in detail.
