Context: It is important to realize that in physics today, we have no knowledge what energy is. We do not have a picture that energy comes in little blobs of a definite amount. It is not that way.

Context: The more you get into material and matter, all you realize is in matter, there is energy. There is a blur between energy and consciousness. All material is conscious to some extent or another. All material can respond to some extent or another to vibrations of energy that is different to energy you learn about in physics. There are all sorts of reliable information now on people and animal being able to be able to effect the operations of machines—even of computers—and I think that has great implications for what goes on between a musician and his instrument. There is a level of reality where there is no time, and there is no space, there is just energy. And we have contact with that through the intermediate layers, so, if the right channels—if the right connections are established, I don’t see why a piece of matter, a piece of broken glass or and old record can’t make contact through this very high level of reality that has access to everything past and future. I suppose my instruments do retain some sort of memory of me. I know that when I’m working on them I feel (not explicitly, I don’t hear voices in my head or anything) that I’m making a connection with it. The circuit diagram, that is then converted into a circuit board, which then becomes a part of an instrument is something that is a record that I made. So I guess in that sense it is something that is certainly a memory.

Context: In mysteries what we know, and our realization of what we do not know, proceed together; the larger the island of knowledge, the longer the shoreline of wonder. It is like the quantum world, where the more we understand its formalism, the stranger that world becomes.

Here's the key: You know you're vulnerable. No other animal knows that. You know what hurts you, because you're vulnerable. And now that you know what hurts you, you can figure out what hurts someone else. And as soon as you know what can hurt someone as, and you can use that, then you have the knowledge of good and evil. Well it's a pretty good trick that the snake pulled because it doesn't seem like the thing that we would have exactly wanted if we knew what the consequence was going to be. As soon as a human being is self conscious and aware of his nakedness, then he has the capacity for evil. That's introduced into the world right at that point."
