...there is pure awareness without experience, experiencer, or content. In hindsight, we call this "a unity-conscious" experience, but during samadhi there is only alert aware empty presence; body, mind, and world have vanished. It is impossible to talk about samadhi because there is no content or experience in that state that can be discussed. After samadhi dissipates, we can say that it was "an experience" only because it had a starting and ending point and had duration.
