Enlightenment and Nirvana are synonymous. "Buddha is said to have entered upon Nirvana when he died. Yet at the same time we are told that Buddha had attained Nirvana already during his life."[AP]

"If thou knowest the destruction of the Sankharas, thou knowest the Uncreated" (Dhammapada); or, as Professor Oldenberg's translator renders it, "Let others pursue the uncreated by their erroneous paths which will never carry them beyond the realm of the created. As for thee, let the attainment of the Uncreated consist in this, that thou reachest the cessation of the created."

Gotama, in a conversation between himself and an unbeliever, said: "Illustrious disciple, Nirvana may be compared to the nothingness defined as the absence of something different to itself. We may justly define Nirvana as that sort of non-existence which consists in the absence of something essentially different."[AQ]

The Metaphysic of Christianity and Buddhism — Part 74

There are to be found several passages in the New Testament which seem to confirm the interpretation given to St. Paul's saying about the "things that are not." Heaven is spoken of as an inheritance that fadeth not away--that is, the "things that are" fade away, but the things that are not do not fade away. The things that are not seen (that are not) are eternal, and the things that are seen (that seemingly are) are temporal.

This it hath not entered the heart of man to fully understand. We only see through a glass darkly; through the web of illusion. "But if we hope for that which we see not, then do we with patience wait for it."

Jesus answering his interrogators, exclaims: "What _house_ will ye build me, or what is the _place_ of my rest?" This was a rebuff to those who endeavoured to localize the illocatable. "The Most High dwelleth not in temples made with hands." "My kingdom is not of this world." Jesus spoke to the people in parable because it was not given to them to understand the mysteries of the kingdom of heaven.

Gotama said: "Whatsoever has not been revealed by me let that remain unrevealed, and what has been revealed let it be revealed."

With reference to the saying of Jesus, "_Multa habeo vobis dicere, sed nunc non potestis portare illa_," St. Augustine remarks: "_Manifestum est non esse culpandum, aliquando verum tacere._"
