“…the most influential journeys I have had have been with Ayahuasca, the vine from the Amazon, the combination of that and mushrooms. They give me the trots and such! It's very much a medicine woman, medicine man's journey drug, where you go inside. It's not a social thing. It's an internal experience. I experiment with things that are usually an internal experience, because that's just what excites me. And yes, it does sometimes give me visions. But my intention when I am doing it is very different than recreational. I don't do it recreationally. I do it to go do inner work, and I'm very clear before I do it what I'm searching for. That way, there's no abuse suffered and I don't rely on it. It's just one more tool that I use sometimes.”

Context: I see you, and you see me. I experience you, and you experience me. I see your behaviour. You see my behaviour. But I do not and never have and never will see your experience of me. Just as you cannot "see" my experience of you. My experience of you is not "inside" me. It is simply you, as I experience you. And I do not experience you as inside me. Similarly, I take it that you do not experience me as inside you.
"My experience of you" is just another form of words for "you-as-l-experience-you", and "your experience of me" equals "me-as-you-experience-me". Your experience of me is not inside you and my experience of you is not inside me, but your experience of me is invisible to me and my experience of you is invisible to you.

Context: A god, as I have said, commanded me to tell the first use also, and he himself knows that I have shrunk from its obscurity. He knows too that not only here but also in many other places in these commentaries, if it depended on me, I would omit demonstrations requiring astronomy, geometry, music, or any other logical discipline, lest my books should be held in utter detestation by physicians. For truly on countless occasions throughout my life I have had this experience; persons for a time talk pleasantly with me because of my work among the sick, in which they think me very well trained, but when they learn later on that I am also trained in mathematics, they avoid me for the most part and are no longer at all glad to be with me. Accordingly, I am always wary of touching on such subjects, and in this case it is only in obedience to the command of a divinity, as I have said, that I have used the theorems of geometry

Variant: Life will give you whatever experience is most helpful for the evolution of your consciousness. How do you know this is the experience you need? Because this is the experience you are having at the moment.
