Ānanda, I will teach you a Teachings exposition called the mirror of The Teachings, equipped with which a Noble Disciple, if he aspires, could by himself declare of himself:

I am one finished with hell, finished with the animal realm, finished with the realm of afflicted spirits, finished with the plane of misery, the bad destinations, the nether world. I am a Stream-Enterer, no longer bound to the nether world, fixed in destiny, with Enlightenment as my destination.

And what, Ānanda, is that Teachings exposition, the mirror of The Teachings, equipped with which a Noble Disciple, if he aspires, could by himself declare thus of himself?

Here, Ānanda, a Noble Disciple possesses confirmed confidence in The Buddha thus: The Perfectly Enlightened One is an Arahant, perfectly Enlightened, accomplished in true wisdom and conduct, fortunate, knower of the worlds, unsurpassed leader of persons to be tamed, Teacher of heavenly beings and humans, The Enlightened One, The Fortunate One.

He possesses confirmed confidence in The Teachings thus: The Teachings are well expounded by The Perfectly Enlightened One, directly visible, immediate, inviting one to come and see, applicable, to be personally experienced by the wise.

He possesses confirmed confidence in The Community thus: The Community of The Perfectly Enlightened One’s disciples is practicing the wholesome way, practicing the straight way, practicing the true way, practicing the proper way, that is, the four pairs of persons, the eight types of individuals — this Community of The Perfectly Enlightened One’s disciples is worthy of gifts, worthy of hospitality, worthy of offerings, worthy of respectful salutation, the unsurpassed field of merit for the world.

He possesses the virtues dear to the Noble Ones — unbroken, untorn, unblemished, unblotched, liberating, praised by the wise, not misunderstood, and leading to concentration.

This, Ānanda, is those Teachings exposition, the mirror of The Teachings, equipped with which a Noble Disciple, if he aspires, could by himself declare of himself.
