菩薩從兜術天降神母胎說廣普經 1.89

1.89

「於是菩薩入大虛空大寂定三昧，觀此三千大千世界，上至無邊無盡剎土，眾生之類識神所趣，思惟分別空無之法，是謂菩薩摩訶薩即於胎中成無上道。

"Thereupon, the bodhisattva enters the samādhi of great space and great quiescent absorption, observing this trichiliocosm up to boundless and inexhaustible buddha-lands, the destinies of the consciousnesses of the kinds of sentient beings, contemplating and discerning the dharmas of emptiness and nothingness. This is called the bodhisattva-mahāsattva realizing the unexcelled path right within the womb.
