淨名經集解關中疏 2.388

2.388

"There are those that perform Buddha-activities through the Buddha's physical body; there are those that perform Buddha-activities through empty space. Sentient beings, in accordance with these conditions, are able to enter disciplined practice." / Zhao says: "For those fond of existence, he preserves the body to display fondness for existence; for those fond of emptiness, he annihilates the body to display emptiness, as explained in the *Guhyakādhipati Sūtra*. Although the marks above reside on the body, the body and marks are not identical; their causes are distinct, hence the Buddha-activities differ."
