We need exaltation, as I said, in order to live; and, as a matter of fact, you may meditate for hours and hours and days and days and months and months and. months, and years and years, doing all the things that were prescribed, and nothing happens. Then all of a sudden you come in contact with a being who is intoxicated himself, and you are carried beyond yourself and in that moment you have done more progress than in all those years of hard work practicing. And that is the reason for the gurus, if they are gurus. The guru is the one who sweeps you off your feet, I mean your personal feet, into Divine Consciousness, who lifts you upon wings of ecstasy. He is the one who performs the fana', that is, the annihilation, of your opinion, and the baqa', which means the eternalization of Divine understanding. I'll say that again: the fana' of opinion, it is zikr, actually, the fana' of opinion in the baqa' of Divine realization.
