Lotus Sutra

“At the time the Bodhisattva Inexhaustible Mind (Aksayamati) straightaway rose from his seat and, baring his right shoulder and facing the Buddha with palms joined, said “O World Honored One! For what reason is the Bodhisattva ‘He who observes the sounds of the world (Avalokitesvara) called observer of the sounds of the world?”

The Buddha declared to the Bodhisattva Inexhaustible Mind “Good man, if in calculable hundreds of thousand of myriads of millions of living beings, suffering pain and torment, hear of this Bodhisattva ‘He who observes the sounds of the world’ and single-mindedly call upon his name, the Bodhisattva He who observes the sounds of the world shall straight away heed their voices, and all shall gain deliverance.”
