Often people are afraid when reading Buddhist books, where the interpretation of Nirvana is given as "annihilation." No one wants to be annihilated, and people are very much afraid when they read "annihilation." But it is only a matter of words. The same word in Sanskrit is a beautiful word: mukti. The Sufis call it fana. If we translate it into English it is "annihilation," but when we understand its real meaning it is "going through" or "passing through." Passing through what? Passing through the false conception, which is a first necessity, and arriving at the true realization.
