大乘起信論略述 2.69

2.69

論。自然而有至遍一切處　述曰。下顯用相。於中有二。初明用染廣。後明用無相。此初也。自然等者。明用染也。與真等者。顯用廣也。妙用難測名不思議。用相巨多名種種用。任運起用名自然有。是則依前法身之體不待作意。任運起相難思業用。用依真起。故同真如等遍一切。

[Treatise:] Spontaneously having ... pervasively in all places.
[Exposition:] Below, the characteristics of function are revealed. In this, there are two parts: first, clarifying that the function is subtle and vast; second, clarifying that the function is free from characteristics. This is the first. 'Spontaneously,' etc., clarifies that the function is subtle. 'Equal to reality' reveals that the function is vast. Wonderful function being difficult to fathom is called 'inconceivable'; the characteristics of function being immensely numerous is called 'various functions'; giving rise to function effortlessly is called 'spontaneously having.' That is, relying on the previous essence of the dharmakāya, without awaiting deliberate intent, difficult-to-conceive karmic functions arise effortlessly. Because function arises relying on reality, it is equal to suchness and pervades everywhere.
