We see ourselves as multiple-faceted begins because we have forgotten our oneness and in that forgetting we made different facets of ourselves. These facets are not good or bad if used by spirit they can help us to remember our oneness however used by the ego we will see ourselves as separate only continuing the narrative of the ego.
How do we start this process of allowing spirit to help us one of the best ways is simply to ask, spirit please use each facet that I have made to help me remember the oneness I am. We can also do some deep questioning and observation of ourselves. We can ask ourselves what facet of myself do I embody a majority of the time? What facet of myself do I deny? What facet do I hide away from everyone and why?
The most important thing to remember is you are not a separate begin with many facets but instead one begins view themselves as as multi-faceted
