菩薩瓔珞本業經 1.75

1.75

「佛子！八、不思議無功用觀。所謂無相大慧方便大用，無有色習無明亦盡，百萬劫事無量佛土事已一念心一時行，現如佛形、一切眾生形，一念心中一時行已，無功用故。

"Son of the Buddha! Eighth, the inconceivable, effort-free contemplation. This refers to signless great wisdom and the great function of skillful means; there are no habit-energies of form, and avidyā is also exhausted. The matters of millions of kalpas and the matters of immeasurable Buddha-lands are practiced simultaneously in a single thought-moment; manifesting forms like those of Buddhas and forms of all sentient beings, practiced simultaneously within a single thought-moment, without effort.
