Making the creator supreme is part of the quest for the ego for a super-identity. The ego identifies with greatness in order to glorify itself. This lays the foundation for Narcissism in religious thought.
The foundation of narcissism in religious thought lies in human nature, specifically the dual existence fabricated by the ego for our convenience.
It is the EGO which is the identified adversary in almost all religious context.
BUT it is only recently that the concept of EGO escaped esoteric circles, clergy, and elitist control. At least for most of us reading in this language.
So if we were to re-examine most mythos under the lamp of CONSCIOUSNESS, we will find many descriptions of the internal battle in EVERY religion we explore. Then we start understanding human spirituality as a shared experience that transcends time, place, language, and pretty much every human difference imaginable.
With this in mind, understanding supremeness in human terms as divine ineffability does not lead to egoic postures like narcissism... Rationality does, which is a direct product of thought and egoic comparison.
True, the supreme identity is based on ego and personality, as reflected in the Catholic religion, image and likeness, moreover in many religions is used to give credit for things that divinity to have more power over their believers, to the point that it becomes the result of the collective human mind that feeds every day and those who have power over the "word of that divinity" use this setting to control all his followers and blind faith ", that explains so much manipulation over time, if only we start to think about what happened with the rules of the Vatican over time, were changing with modernism and covering his lies also in many ways. Buddhism such is otherwise seeks to realize your own divinnidad through d ela overcoming EGO and Personality. I think that at some point all those beings evolved as Mohammed, Jesus, Shidarta, etc. had the knowledge of overcoming EGO but his followers were misrepresenting knowledge over time, and only few could keep those esoteric teachings. It is now possible to regain that knowledge, people with strange powers assumptions as Edgar Cayce, HP Blavatsky, Nostradamus, etc. mention that you can get everything through the Akasha, then on that part of metaphysical investigation we stay?
Yes I agree, but religion and a supreme being are also a manifestation of man's frailty, weakness, fear and feeling of helplessness. Man "creates" a super being that will give back life to a loved one, protect one from natural disasters and calamities, rescue him from poverty, violence and threats, and bring him to a heavenly paradise.
