Physicality

All existences are physical existences. 

The force-field of a magnet is invisible to the human eye, but non-the-less its physical existence is incontrovertible. The awareness which we find in all life is also a field phenomenon, and in the same way as magnetism, awareness is dependent upon specific agregates of matter for its activity. In much the same way that magnatism is a much utilized yet wholly mysterious phenomenon known only by its affects, the Awareness which is the substrate of all identity is a wholly mysterious phenomenon known only by its affects. 

The "What" that is the "Who" of our daily life is a field of Awareness, and our humanity is the form made necessary to its existence: our humanity is a vehicle and an abode and a means of proliferation. Awareness (like magnatism) has only one quality: Awareness. In every creature we find Awareness, which is the very stuff of life, totally identified with the vehicle that maintains it. It is quite inevitable that this should be so. It is also quite inevitable that at a certain point in the evolution of living organisms, Awareness should achieve self-recognition and become the seat of identity, thus entering into an entirely new relationship with the natural world.

It is not too great a stretch to consider that such an awakening might be the entire thrust of evolution to begin with.
