1.59

問：若以觀心為兩序者，豈不顛倒？答：立名之便故言觀心，修行之便即是心觀，類前事義其理顯然。

Question: If one takes the contemplation of mind to be the two prefaces, is that not inverted? Answer: For the convenience of establishing the name, one says 'contemplation of mind'; for the convenience of cultivation and practice, it is 'mind-contemplation'. By analogy with the previous matters and meanings, the principle is obvious.
