Those of my disciples who completely understand my instructions realize the undefiled freedom of heart and freedom by wisdom. And they live having realized it with their own insight in this very life due to the ending of defilements. Of those disciples who only partly understand my instructions, some, with the ending of the five lower fetters, become reborn spontaneously. They are extinguished there, and are not liable to return from that world. Some, with the ending of three fetters, and the weakening of greed, hate, and delusion, become once-returners. They come back to this world once only, then make an end of suffering. And some, with the ending of three fetters, become stream-enterers, not liable to be reborn in the underworld, assured, destined for awakening. And so the going forth of all those gentlemen was not in vain, was not barren, but was fruitful and fertile.” That is what the Buddha said. Delighted, the centaur Pañcasikha approved and agreed with what the Buddha said. He bowed and respectfully circled the Buddha, keeping him on his right, before vanishing right there.
