AUO and all individuated consciousness entities have free will. It is a part of being consciousness. Even a fundamental particle has free will. Just not much room to exercise it. If every thing is consciousness, then every thing is conscious. What is different between you and a fundamental particle is the decision space. Fundamental decision space is fundamentally limited to only the functions of the fundamental. In the case of a fundamental particle, the decision space is completely limited to the singular space-time PMR experience in a singular (non-complex) being similar in scope to AUO. The difference between a fundamental particle and AUO is the amount of presence of being. In PMR this is measurable as mass. For all practical PMR instances, a black hole and a fundamental particle have only presence as a difference. Both are fundamental "particles" in PMR from our point of view. But you, as a human being are much much more complex than either the particle or the black hole. The decision space of a fundamental particle is limited to one kind of awareness in one time and one space. It has free will, but not many choices to make. How much free-will a being has is dependent upon its complexity. The more complex the being, the greater the number of differences in awareness there can be. The greater the awareness, the more decision space exists in any situation that the being is aware of. So the decision space is proportional to the complexity of being, and so too then is the free-will.
Everything is not consciousness (in the sense you are saying), if one uses the concept of a virtual reality. A fundamental particle is just as virtual as your brain, is your brain consciousness? No, it is virtual.
I think your example of fundamental particles can be used as an analogy or metaphor, a single particle can be seen as a single bit, but the single bit is not conscious. Consciousness is not contained in a single bit, or particle, but in a complex
organization or pattern of these. Complex meaning "The whole is more than the sum of it parts".
I agree with the complexity part, but complexity does not start at a single bit or particle.
Free will in a single fundamental particle? It has no sentience, it is virtual, and not consciousness by the definition agreed on. See slide 27 http://www.mybigtoe.com/CaliforniaWorkshopSlides.pdf
Let us say AUM is thinking or dreaming this reality will live in. Is the thought thinking? Is the dream, dreaming?
Nope, and that is my point :)
