According to Osho, the memory of an experience is indeed an experience—but of the past. Remembering creates a split: the one who recalls and the thing recalled; thus you are separate from it. In living experience there is no gap—you simply are. Seeing this shifts you from secondhand recollections to firsthand presence and awareness.
A memory is you thinking about what happened before, which makes you separate from it, while the original moment had no separation—you were just in it.
