Self, and everything outside the self. Self being your mind, your perception. Outside the self, meaning reality....the world around you.....everything else except you in existence.
Many spiritual people think of themselves as this pilot that has control of a spaceship and is maneuvering through an obstacle course, trying to do the right thing.
Light, and darkness. They go together, they are the same. Light with no darkness is not light, it is just...something that cannot possibly exist. Light and dark coexist together....each other spring forth each others existence. More importantly, OUR perception and definition of light and darkness defines them and springs forth their existence.
If a tree falls in a forest and no one is there to hear it, it doesn't make a sound because sound only exists in your mind. All the same, if a tree falls in the forest, you are the tree! But just as light and darkness, self and everything outside the self are the same, and cannot possibly exist without the other. Sound is nothing without silence, wet without dry, good without evil...but more importantly, neither are possible without the self, and the not self, they're coexisting and self aware of the mirror on a mirror reflection of itself spinning new realities off into fractal tangents.
The self, and everything outside the self is the same thing....the face of god personified in time and space.
So yes, nature is church like everything else.....
