金剛三昧經論 3.74

3.74

經曰　「長者！如是三行，總攝眾門，一切法門無不此入。入是行者不生空相，如是入者可謂入如來，入如來者入入不入。」

The sūtra says: “Elder! These three practices completely subsume all gates; there is no dharma-gate that does not enter here. One who enters these practices does not generate the sign of emptiness. One who enters in this way can be said to have entered the Tathāgata; one who has entered the Tathāgata enters entering non-entering.”
