大乘起信論略述 2.77

2.77

論。復次凡夫所見至說為應身　述曰。次下第二重牒分別。於中有二。先應。後報。此初也。前明報身。通依凡小所見而說。今欲簡凡異小。所見重顯應身。二乘見佛是聖人身。凡夫見者六道各異。皆非出世相同苦諦。是故名為非受樂相。果不稱因。說之為應。

[Treatise:] Furthermore, what ordinary beings see ... is called the transformation body.
[Exposition:] Next, the second [part] re-takes up and differentiates [the bodies]. In this there are two: first, the transformation [body]; next, the enjoyment [body]. This is the first. Previously, in explaining the enjoyment body, it was spoken of generally in reliance upon what ordinary beings and the lesser [vehicle] see. Now, wishing to distinguish ordinary beings and set apart the lesser [vehicle], what is seen is set forth again to reveal the transformation body. The two vehicles see the Buddha as the body of a noble person; what ordinary beings see varies across the six destinies. None of these are supramundane marks; they are identical with the truth of suffering. Therefore, they are called "marks not of receiving bliss." Because the fruition does not correspond to the [true] cause, it is spoken of as "transformation."
