I have heard that on one occasion the Blessed One was staying near Savatthi, in Jeta's Grove, Anathapindika's monastery. Now at that time the Blessed One was instructing urging, rousing, and encouraging the monks with Dhamma-talk concerned with Unbinding. The monks — receptive, attentive, focusing their entire awareness, lending ear — listened to the Dhamma.
Then, on realizing the significance of that, the Blessed One on that occasion exclaimed:
There is that dimension where there is neither earth, nor water, nor fire, nor wind; neither dimension of the infinitude of space, nor dimension of the infinitude of consciousness, nor dimension of nothingness, nor dimension of neither perception nor non-perception; neither this world, nor the next world, nor sun, nor moon. And there, I say, there is neither coming, nor going, nor staying; neither passing away nor arising: unestablished, unevolving, without support (mental object).1 This, just this, is the end of stress.
