“Everything is energy and that's all there is to it. Match the frequency of the reality you want and you cannot help but get that reality. It can be no other way. This is not philosophy. This is physics.”

The close of his Nobel lecture: "The Statistical Interpretations of Quantum Mechanics" (11 December 1954) http://nobelprize.org/nobel_prizes/physics/laureates/1954/born-lecture.html
Context: Can we call something with which the concepts of position and motion cannot be associated in the usual way, a thing, or a particle? And if not, what is the reality which our theory has been invented to describe?
The answer to this is no longer physics, but philosophy. … Here I will only say that I am emphatically in favour of the retention of the particle idea. Naturally, it is necessary to redefine what is meant. For this, well-developed concepts are available which appear in mathematics under the name of invariants in transformations. Every object that we perceive appears in innumerable aspects. The concept of the object is the invariant of all these aspects. From this point of view, the present universally used system of concepts in which particles and waves appear simultaneously, can be completely justified. The latest research on nuclei and elementary particles has led us, however, to limits beyond which this system of concepts itself does not appear to suffice. The lesson to be learned from what I have told of the origin of quantum mechanics is that probable refinements of mathematical methods will not suffice to produce a satisfactory theory, but that somewhere in our doctrine is hidden a concept, unjustified by experience, which we must eliminate to open up the road.

From the film Moog (2004)
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.
