I relate very strongly to the third and fourth paragraph.....neuroscience proving that our set brain circuits impact our view of self and others. I have lived a life accepting toxicity in relationships as the norm and it is indeed hard to reform those perspectives.
Spirituality I see differently.....the human, the life we lead, is one thing...our intrinsic self...the spirit....something else and elusive to the human mind. There is much we simply cannot grasp about eternity....the spiritual....as we are currently locked in the human condition.
