大方便佛報恩經 7.7

7.7

"Furthermore, the bodhisattva cultivates mahopāya, knowing kindness and repaying kindness. When the Buddha was at the Bamboo Grove monastery, there was a bhikṣu whose body suffered from foul sores; pus and blood constantly flowed all over his body, and he was despised by the multitude, with no one approaching him. He lived in a dilapidated hut on the periphery. At that time, the Tathāgata demonstrated his spiritual power, concealing himself from the great assembly so that none knew. The Tathāgata went alone to where the sick bhikṣu was, and according to what was needed, drew water to wash him. Having considered this, he caused all the devas of the desire realm to become aware of it. Śakra Devānām Indra, surrounded before and behind by his retinue of immeasurable hundreds of thousands, rained down various celestial flowers, played diverse celestial music, and stayed in the open sky. At that time the king of Trāyastriṃśa held in his hands a wondrous bath pitcher adorned with a hundred merits, filled to the brim with pure water of great compassion. He then stepped forward to welcome [the Buddha], bowed his head to the Tathāgata's feet, and withdrew to stand to one side.
