金剛三昧經論 2.124

2.124

經曰　爾時眾中有一菩薩名曰大力，即從座起前白佛言：「尊者！如如所說五空出入無有取捨，云何五空而不取捨？」

The sūtra states: At that time, in the assembly there was a bodhisattva named Mahābalavān, who immediately arose from his seat, stepped forward, and addressed the Buddha, saying: "Honoured One! As it has been said in accord with thusness, regarding emerging and entering the five emptinesses there is neither grasping nor abandoning. How is it that with the five emptinesses there is neither grasping nor abandoning?"
