Spirit and energy are, in my view, the same concept: the verb to be. They are pure existence, which is an action and not an object, and thus neither can be observed directly. However, they can be observed and known by their effects.
To be is what all things do, even if they do little else. Thus all things are spirit-infused.
When we ourselves do nothing but notice that we are being, we are spending time with spirit. It is as easy as that. When we add gratitude and awe, we are giving spirit our worship and devotion. To simply be is itself a prayer when we know the true wonder of being.
