Everything appears separate from everything else….and it is, but it’s also utterly connected by unseen/unperceived by our normal senses electro-magnetic/photonic/quantum particles that are the actual underlying realities that continually swirl around and between us. Thus the oneness one feels in the heightened state of reality referred to in all of the world’s major wisdom traditions is the more basic and full reality.
There are undoubtedly countless other examples of such paradoxes, and the only way to resolve them is to thoroughly consciously understand both sides of them.
