仁王護國般若波羅蜜多經 2.31

2.31

「復次，遠行地菩薩摩訶薩，修無生忍，證法無別，斷諸業果細現行相，住於滅定，起殊勝行，雖常寂滅，廣化眾生——示入聲聞，常隨佛智；示同外道，示作魔王，隨順世間而常出世。於十阿僧祇劫，行百萬三昧，善巧方便廣宣法藏，一切莊嚴皆得圓滿。

"Furthermore, the bodhisattva mahāsattva of the Far-Reaching Ground cultivates the patience of non-arising and realizes the non-differentiation of phenomena. Severing the subtle manifest aspects of karmic fruits, they abide in the concentration of cessation and generate extraordinary practices. Although constantly tranquil, they broadly transform sentient beings: appearing to enter the ranks of śrāvakas, yet constantly following the Buddha's wisdom; appearing identical to non-Buddhists, appearing as demon kings, conforming to the mundane world yet constantly supramundane. Over ten asaṃkhyeya kalpas, they practice a million samādhis, skillfully and with expedients broadly proclaiming the treasury of Dharma, bringing all adornments to perfection.
