四明十義書 2.31

2.31

且上人定將何等法門為觀心之義？若以純明理觀為觀心義者，十法既非三種三昧，既不揀示陰境，既不明十乘觀法，安得輒名純談理觀？豈非全無理觀觀心義耶？

Then what kind of teaching gate does the Venerable One definitively take to be the meaning of contemplating the mind? If purely clarifying principle contemplation is taken as the meaning of contemplating the mind, since the ten dharmas are not the three kinds of samādhi, do not select and show the object of the aggregates, and do not explain the ten vehicles of contemplation, how can they be casually named as purely discussing principle contemplation? Is this not entirely lacking the contemplation-of-mind meaning of principle contemplation?
