菩薩從兜術天降神母胎說廣普經 1.19

1.19

Thereupon, by means of his supernormal powers, the Bhagavat manifested sitting, reclining, and walking within the body of his mother Māyā. He spread a great, high seat, eighty yojanas in length and breadth, with gold and silver stairs and railings, celestial silks and celestial canopies suspended in empty space, and the singing of music beyond reckoning. Furthermore, by his supernormal powers, eighteen thousand lands away from this Sahā World to the east, bodhisattva mahāsattvas all came gathering like clouds; so it was likewise in the south, west, north, and the four intermediate directions. There were also bodhisattvas possessing supernormal powers from sixty-two billion lands below who also came to the great gathering; bodhisattvas of the empty realms from seventy-two billion lands above also came gathering like clouds, entering the womb chamber.
