Duality, specifically habitual duality is the curse word of human history and human psychology. Its the lesson of the fall of Man, the story of the consciousness of ethics and the necessity of personal pursuit of trinity/integrative unity-oneness/grace. https://www.amazon.com/dp/B07PLNJLRN/ref=sr_1_1?keywords=wisdomics-Gracenomics&qid=1552358772&s=books&sr=1-1-catcorr
Being religious CAN be a good…if you contemplate grace/samadhi/nirvana/etc., which is the active expression of love. Unfortunately though, too often religion ends up being just setting up another duality/problem of my religion is right and yours is wrong. Grace is thirdness/unity/oneness/solution.
Grace is the doctrine of not clinging to doctrines.
