四明十義書 1.138

1.138

《義例》既云淨心歷法任運泯合。何曾加行？以此驗是觀成淨心遍歷也。又文中自出修內觀所以，云當知一切由心分別，諸法何曾自謂同異。既推過在心，則但於內心修觀。外色諸法既本無同異分別，則不須加功而修觀法。

The Yili, however, states that the pure mind traverses dharmas, naturally dissolving and merging. Where were expedients applied? From this it is proven that this is traversing universally with a mind purified through completed contemplation. Furthermore, the text itself sets forth the reason for cultivating inner contemplation, saying: 'One should know that everything is discriminated by the mind; how could dharmas ever speak of themselves as identical or different?' Since fault is located in the mind, one cultivates contemplation only in the inner mind. Since external form and other dharmas fundamentally have no discrimination of identity and difference, one need not apply effort to cultivate the contemplation method [on them].
