四明十義書 2.142

2.142

如將此玄十種三法謂純談理觀，豈非全不知理觀是常坐等三種三昧？只見《發揮》云純談真性，便約此立為純談理觀。

For instance, when you asserted that the ten threefold dharmas of this *Xuanyi* 'purely discuss principle contemplation', is this not because you were completely ignorant that principle contemplation refers to the three kinds of samādhis such as the constantly sitting [samādhi]? Merely seeing that the *Fahui* says 'purely discusses the true nature', you thereupon established it based on this as 'purely discusses principle contemplation'.
