What "name" best fits this type of belief system?

A. All Life in Existence is Connected. Where all life can be merged into "the" original entity. "Not children of God" for lack of better words, but rather, like a puzzle, we are equal (keyword), albeit broken up pieces of one enormous puzzle.

B. The purpose of this original entity, to simply experience every possible thing from every possible perspective, by breaking itself up into the various types of existences we know of today both familiar and alien.

C. A Constant Cycle of "souls" returning to the epicenter of this entity, to be recycled and reincarnated back into reality.
