And the concept of a higher beeing... and in general esoteric things, and least in the common understanding of the word, not so much.
That beeing said, I am quite open and interested in esoteric things(even though I prefer the word spiritual), I just wanted to point out a more likely explanation to the op. Not ridiculing his version.
additionally I would refute your claim that the subconscious (or really anything to do with consciousness) is well understood by science. it is acknowledged as being a thing that exists and just as readily acknowledged as being a thing that is poorly understood, at least from a materialist science perspective.
the models of consciousness that produce more thorough and well-explored theories tend to come from spiritual traditions, such as Buddhism, rather than materialist traditions.
And I did not said that subconscious "is well understood by science", just that it is broadly accepted that it exists, unlile gods.
Less esoteric explanation: Or it is a call from deep within, the subconscious. But with the same implications. And that medications might not be that helpfull for that purpose.
