There is, monks, that plane where there is neither extension, nor motion, nor the plane of infinite ether…. nor that of neither-perception-nor-non-perception, neither this world nor another, neither the moon nor the sun. here, monks, I say that there is no coming or going or remaining or deceasing or uprising, for this is itself without support, without continuance in samsara, without mental object – this is itself the end of suffering.
There is, monks, an unborn, not become, unmade, uncompounded, and were it not, monks, for this unborn, not become, not made, uncompounded, no escape could be shown here for what is born, has become, is made, is compounded. But because there is, monks, an unborn, not become, unmade, uncompounded, therefore an escape can be shown, for what is born, has become, is made, is compounded.
– The Buddha. The Udana Scripture
