大方便佛報恩經 6.7

6.7

Nanda, hearing the Buddha demonstrate, instruct, benefit, and gladden him with various expositions of the Dharma, rejoiced in his heart. He straightened his robes and prostrated himself with head and face at Upāli's feet. At that moment, heaven and earth shook in six ways, his body and mind became pliant, he attained his own benefit, and that which was to be done was accomplished.
