注維摩詰經 9.76

9.76

肇曰：佛慧如空，應形猶地，不以地異而異空，不以空一而釋地也。生曰：色身是外應之有，出無閡慧中，而無閡慧無色身也。

[Seng]zhao says: The Buddha's wisdom is like space, and the responsive forms are like the ground. One does not differentiate space on account of the differences of the ground, nor does one dismiss the ground on account of the oneness of space. [Dao]sheng says: The physical body is the existence of external response, emerging from within unobstructed wisdom, yet unobstructed wisdom has no physical body.
