I have a picture of a geologic formation that refutes the Flood myth. It is still a bit of an awe inspiring image for me because I can understand the processes involved rather well.
That's a good description of an authentic spiritual experience. It's always when one is contemplating reality with understanding, which leads to a sense of connection to our world with an associated sense of mystery, awe, and gratitude.
It occurs when gardening, when listening to moving music, when contemplating the night sky, when contemplating the mystery of existence. It's always about what is here around us. Cutting oneself off from that and redirecting one's attention to imaginary realms and their denizens or unseen "dimensions" is pretty much the opposite of that.
Why would I want to put that poison in my body? I’m healed now and not sick anymore. People drink and drug, why? If you’re doing well already why would you need something to make you feel better?
That's how I feel when somebody tries to bring me back to theism, my escape from which was very much like quitting cigarettes. One senses the dysphoria of withdrawal and having one's attention repeatedly pulled back whether wanting a cigarette or, as I also did, find myself praying to a god I no longer believed in for much of a year ("Jesus, if I'm making a mistake, if you're really there, please give me a sign"). Like you, I feel like I was delivered from a kind of bondage. So, when they tell me to keep looking for Jesus, just try harder this time, my answer is about the same as yours. Why would I want to poison my mind with religion again? I'm better off than I was when I did. As you say, "If you’re doing well already, why would you need something to make you feel better?"
All Einstein's quotes against belief in God are only against belief in personal God, Bible, traditional religion
Once you strip God of personhood, whatever it is you are talking about should be called that. Look at the mess Einstein made with his injudicious use of the word to refer to the laws of nature. That name is good enough if that's what you are referring to. Or call it nature. Or even Mother Nature, a term which doesn't refer to a sentient entity and would never lead to an argument about what that phrase meant. My definition of a god is a sentient creator of universes, and I only use the word when referring to such an idea to avoid this kind of ambiguity.
