四明十義書 1.13

1.13

且三種觀法皆顯心性，但事法二觀既託事義觀心，及附法相觀心，且非直顯。唯約行觀直，於陰心顯三千性，方名直顯心性。據此兩書，定判此玄十種三法已是約行之觀，故可廢今附法觀心也。

Now, all three kinds of contemplation methods reveal mind-nature; however, phenomenal and doctrinal contemplations, since they contemplate the mind by entrusting to phenomenal meanings and appending to doctrinal characteristics, do not directly reveal it. Only contemplation according to practice, directly revealing the nature of the three thousand [realms] upon the mind of the aggregates, is called directly revealing mind-nature. According to these two treatises, you definitively judge that the ten kinds of threefold dharmas in this Xuanyi are already contemplation according to practice, and therefore the present [passage on] contemplating the mind by appending to teachings can be abolished.
