God concepts - I’ve borrowed the term from Carl Jung, and am using it in the manner he did - refers to the way diverse cultures and individuals have related to the infinite and the divine; as far as I’m aware every human culture has a history of such relationships.
Jung was mostly concerned with the therapeutic value of spiritual experiences; the point being that throughout human history, people have recorded life changing spiritual experiences, which have enabled them to turn existential crises into revitalising personal transformation. Whether they put these experiences down to Yahveh, Siva, Christ, Krishna, the Great Spirit, an underlying creative intelligence, or even self hypnosis, necessarily varies from culture to culture and person to person.
And yes, many of us do need this spiritual support, and would no more choose to neglect the spirit, than we would the mind or body.
