Oneness is when there isn't another. Oneness is—there is only this. There is no that over there, there is only this. And that's all there is. There is only this, and as soon as you say what this is, you've just defined what it's not. This is only realized in the utter demolition of everything that it's not. Then that awakening is an awakening outside of everything that comes and goes. It is a total waking up outside of time.
