菩薩從兜術天降神母胎說廣普經 1.83

1.83

"Abiding in the third dhyāna, he observes the categories of sentient beings and is able to distinguish them all: perishing there and being born here, perishing here and being born there; he knows his own past lives, and also knows the places whence they have come—the kṣatriya clan, the brāhmaṇa clan, the householder clan, the elder clan; these are practitioners who should act, these are practitioners who should not act; these should receive the fruit, these should not receive the fruit; inhalation and exhalation, non-inhalation and non-exhalation; these four smṛtyupasthānas, four samyakprahāṇas, indriyas, balas, ṛddhipādas, bodhyaṅgas, and the eightfold path; this person will receive prophecy to become a buddha in such-and-such a country, in such-and-such a place, among such-and-such sentient beings—he knows all of this completely. This is called the bodhisattva obtaining a pure mind in the stage of the third dhyāna.
