大般涅槃經集解 66.52

66.52

Sengliang states: "Having severed the residual habits of fetters and extinguished gross afflictions, the explanation of permanence differs from the permanence of the final body." Baoliang states: "Since one remains exclusively in contemplation without emerging or entering, the name of permanence remains."
