菩薩從兜術天降神母胎說廣普經 1.88

1.88

「或有菩薩入非想非不想處三昧，觀此三千大千世界眾生識神所趣，生者、滅者，青、黃、赤、白有長有短，令彼眾生使知壽盡，即於胎中成無上道。

"At times, a bodhisattva enters the samādhi of the sphere of neither-perception-nor-non-perception and observes the destinies of the consciousnesses of beings in this trichiliocosm—those who arise and those who cease, blue, yellow, red, and white, long-lived and short-lived—causing those sentient beings to know when their lifespans are exhausted, realizing the unexcelled path right within the womb.
