What if every person you encountered in life is an externally projected aspect of your ego? Supposed that the people around you are internal conflicts personified, named and assigned a role in your life to guide you through a process of character refinement and soul development.

Or would you double down and fight against yourself? However you respond, what does that say about how you feel about your Self?
