What is ecstasy? The boy banging on the keyboard feels an enthusiasm (or a sorrow, or a delight), and the emotion rises to such a pitch of intensity that it becomes unbearable: the boy flees into the state of blindness and deafness where everything is forgotten, even oneself. Through ecstasy, emotion reaches its climax, and thereby at the same time its negation (its oblivion).
Ecstasy means being “outside oneself,” as indicated by the etymology of the Greek word: the act of leaving one’s position (stasis). To be “outside oneself” does not mean outside the present moment, like a dreamer escaping into the past or the future. Just the opposite: ecstasy is the absolute identity with the present instant, total forgetting of past and future. If we obliterate the future and the past, the present moment stands in empty space, outside life and its chronology, outside time and independent of it (this is why it can be likened to eternity, which too is the negation of time).
