菩薩從兜術天降神母胎說廣普經 4.53

4.53

'Furthermore, a bodhisattva-mahāsattva in an instant can make the trichiliocosm become a water element, just like a bhikṣu who has attained dhyāna contemplating an immeasurable water element, wherein water-dwelling creatures, giant softshell turtles, iguanas, tortoises, and freshwater turtles suffer no harm or disturbance, accumulating merits across kalpas that neither decay nor rot. This is called the bodhisattva-mahāsattva entering the water-element samādhi. Or there are sentient beings who, seeing the bodhisattva enter concentration, think it is water, and throw tiles, stones, grass, and wood into the water at the concentrated bodhisattva; yet the bodhisattva's mind is like space, unaware of any disturbance. This is called the power of the bodhisattva-mahāsattva entering the water element.
