大通方廣懺悔滅罪莊嚴成佛經 2.32

2.32

"Good son, there are furthermore four dharmas by which one does not sever buddhadhātu. What are the four? First, for the sake of sentient beings, not regressing from one's original vow; second, receiving faith and practicing giving; third, possessing great aspiration and vigorous effort; fourth, constantly being able with a profound mind to practice the Buddha-path. These are named the four. When a bodhisattva-mahāsattva travels among the three realms, he carries out various practices to benefit sentient beings, ever cultivating what is supramundane without severing the buddhadhātu."
