菩薩從兜術天降神母胎說廣普經 1.85

1.85

「於是菩薩入空處三昧，觀此三千大千世界眾生之類心識，修淨法離縛著無所戀慕，能自住壽一劫、二劫至無數劫，於某劫中教化眾生。生者、滅者漸漸將導獲清淨道，即於胎中成無上道。

"Thereupon, the bodhisattva enters the samādhi of the sphere of boundless space and observes the mental consciousnesses of the kinds of sentient beings in this trichiliocosm. Cultivating the pure Dharma, free from bonds and attachments, and longing for nothing, he can maintain his own lifespan for one eon, two eons, up to countless eons, teaching and transforming sentient beings in a given eon. Gradually guiding those who arise and cease so that they attain the pure path, he realizes the unexcelled path right within the womb.
