ماجهيما نيكايا 3:31
SUJATOSanti, bhikkhave, bhikkhū imasmiṁ bhikkhusaṅghe pañcannaṁ orambhāgiyānaṁ saṁyojanānaṁ parikkhayā opapātikā tattha parinibbāyino anāvattidhammā tasmā lokā—
In this Saṅgha there are mendicants who, with the ending of the five lower fetters are reborn spontaneously. They are extinguished there, and are not liable to return from that world.
