菩薩從兜術天降神母胎說廣普經 1.32

1.32

The Buddha told Maitreya: "If there is no physical form, who among these sentient beings is there to confer prophecy, and who is there to receive prophecy? How does the bodhisattva proceed to the foot of the tree, sometimes walking back and forth, sometimes entering samādhi? How does the bodhisattva contemplate his own bodily marks and contemplate the bodily marks of others? How does the bodhisattva manifest taking seven steps, declaring of himself that he has attained Buddhahood and subjugated all māras? How does the bodhisattva adorn and cultivate the bodhimaṇḍa, inviting all the sentient beings of the ten directions?"
