The Noble Mahāyāna Sūtra of Aparimitāyur­jñāna

The Buddha, while at the Jetavana in Śrāvastī, tells Mañjuśrī of a buddha realm far above the world, in which lives the Buddha Aparimitāyur­jñāna. He states that those who recite, write, hear, and so on, the praise of this buddha, or make offerings to this text, will have numerous benefits, including a long life and a good rebirth. As vast numbers of buddhas recite it, the mantra, or dhāraṇī, of this buddha is repeated numerous times. This is the best known of the two versions of this sūtra in the Kangyur.
