又大悲經云。佛告阿難。於我法中但使性是沙門。污沙門行。自稱沙門。形似沙門。當有被著袈裟衣者。於此賢劫彌勒為首。乃至最後盧遮如來。彼諸沙門如是千佛。於無餘涅槃界。次第當得入般涅槃無有遺餘。何以故。如是一切諸沙門中乃至一稱佛名一生信者。所作功德終不虛設。阿難。我以佛智測知法界。非不測知。阿難。所有白業得白報。黑業得黑報。若有淨心諸眾生等。作是稱言南無佛者。彼人以是善根必定得近涅槃。何況值佛親承供養。

Furthermore, the *Mahākaruṇā-sūtra* states: The Buddha told Ānanda, “In my Dharma, so long as someone is a śramaṇa by disposition, defiles the conduct of a śramaṇa, calls himself a śramaṇa, looks like a śramaṇa, and comes to wear the kāṣāya robe—in this Bhadrakalpa, beginning with Maitreya and ending with the final Tathāgata Vairocana, across these one thousand buddhas, all those śramaṇas will successively enter parinirvāṇa in the realm of nirvāṇa without remainder, without exception. Why is this? Among all such śramaṇas, even if they have only once invoked the Buddha's name and once given rise to faith, the merit they have created will ultimately not be in vain. Ānanda, by the Buddha's wisdom I fathom and know the Dharmadhātu; there is nothing I do not fathom and know. Ānanda, all white karma receives white retribution, and black karma receives black retribution. If there are living beings of pure mind who invoke and say, ‘Namo Buddhāya,’ by virtue of that root of goodness they will certainly draw near to nirvāṇa—how much more so if they encounter a buddha and attend upon and make offerings to him in person!”
