太子瑞應本起經 1.10

1.10

「菩薩已得記言，疑解望止；霍然無想，寂而入定。便逮清淨不起法忍，即時輕舉，身昇虛空，去地七仞，從上來下，稽首佛足。見地濯濕，即解皮衣，欲以覆之，不足掩泥，乃解髮布地，令佛蹈而過。佛又稱曰：『汝精進勇猛，後得佛時，當於五濁之世，度諸天人，不以為難，必如我也。』

"Having received the words of prediction, the bodhisattva's doubts were dispelled and his yearnings ceased; instantaneously he was without discursive thought, and he entered serene concentration. He thereupon attained the pure forbearance of the non-arising of dharmas. At that moment he lightly rose into the air, ascending seven fathoms above the ground; coming down from above, he bowed his head to the Buddha's feet. Seeing the ground was muddy and wet, he took off his deerskin garment, wishing to cover it, but finding it insufficient to cover the mud, he untied his hair and spread it upon the ground, causing the Buddha to step upon it as he passed. The Buddha praised him again, saying: 'You are energetic and valiant. Later, when you attain buddhahood, you shall deliver all devas and humans in an age of the five defilements without regarding it as difficult, surely just as I do.'
