With the advent of Quantum Theory, it has in fact become apparent that instead of spirit/energy being a separate, higher component that merely occupies the physical, it is in fact the basic fiber out of which all things are woven, including the physical.
Even the most solid, immovable objects are composed of energy and empty space- and our ability to sense them is made entirely of charges that attract and repel each other, as they vibrate and entrain their frequencies to achieve some kind of equilibrium.
We find, that instead of flesh, we are rhythm and light!- and that spirit, as such, is simply the template that organizes the frequencies of which we are composed, without which the "flesh" disintegrates.
We are led to understand that just as we are not simply an elegantly designed vessel created to contain a sublime ethreal substance, we are not simply order struggling to maintain uniformity in a battle with chaos. We are both pattern AND chaos, in a never-ending dance of change and temporary stasis.
Chaos is not the enemy, just as shadow is not the enemy. Chaos is important, because it brings change. Chaos introduces movement into an otherwise frozen and unchanging situation. An element of chaos can be what brings new energy into an otherwise stagnant situation- just as shadows add interest and contrast to the presence of light. Without shadows- light is glaring and harsh. With shadow, comes interest, restfulness, and sometimes challenge.
