四明十義書 2.101

2.101

況予《扶宗記》中以觀妄念為宗，故云：一念識心為境，用三觀觀之，使性德開發，惑滅果成。豈可純談法性，便不論觀心？又云：雖三道本來真淨、諸法當處圓融，其如三惑浩然、二死重積，苦不研心作觀，何由親證如上諸法？

Moreover, in my Fuzong ji I took contemplating the deluded thought as the core doctrine, thus saying: 'Taking a single thought of the conscious mind as the object, one contemplates it using the threefold contemplation, so that the inherent virtues of the nature unfold, delusions are extinguished, and the fruit is achieved. How could one purely discuss dharmatā and thereby not address contemplating the mind?' It also says: 'Although the three paths are fundamentally truly pure and all phenomena are right where they stand completely integrated, given that the three delusions are surging and the two types of death are heavily accumulated, if one does not investigate the mind to practice contemplation, by what means can one personally verify the aforementioned phenomena?'
