四明十義書 2.226

2.226

今來義狀，却云由彼歷別科中從實開權，明三教三軌。及類通中，援引文煩，兼非直對經題解釋，慮讀者忘其觀行，故云合有觀心。

In your present statement of points, you instead claim: 'Because within that section of successive progression [the Buddha] opened the expedient from the real, clarifying the three tracks of the three teachings; and within the section of categorizing and interfusing, citing citations made the text cumbersome, and furthermore it was not directly interpreted in relation to the sūtra title; fearing that readers would forget their practice of contemplation, it was therefore said that there ought to be contemplation of the mind.'
