Let's be logical for a second. When you look at the world you see that people whose parents were Christians and grew up exposed to Christian ideas turn out, generally speaking, to be Christians and so on for every other religion in the world. Nobody who never heard of Hinduism, for example expresses a belief in Indian Deities. Every religious person, generally speaking believes in the religion he was raised around and in.
Logic tells you, therefore, that whatever it is you believe is an accident. All the religious people in the world just happened to be born in the only true religion, their own. Logic tells us, therefore, that if you think you know the true religion you are completely wrong. If you were born elsewhere or in a different time you would believe some completely different only truth.
Logically therefore, religion is just an accretion of horse poo, except for the fact that every were you go in any time there is always some religion. So something in the human animal keeps making up regions that are the absolute truth and therefore obviously not the truth at all.
Logically, therefore, the truth is that man invents religions, millions of them endlessly and all of them are the only way.
Logically, then, some people, the folk who start religions, are having some sort of experience, prefrontal lobe epilepsy, chemically induced hallucinations, meditatively induced brain function alteration, psychic vision, discourse with higher beings, mental illness, extreme mental health, or something or other that alters their consciousness is some way as to produce experiences that create a sense of finality, certainty, and meaning, some deep psychological sense of well being and connection with life that induces them to want to share this with others.
Logically then, God, Nirvana, the great Spirit, Atman, all the millions of names associated with this mental sense are just arrows pointing to the fact that contained within the human experience is the potential to experience something big.
I would call it the ending of duality and entry into being in the now, a state of undivided consciousness where what is is what is conscious. It is a state of consciousness in which the sense of self disappears and love begins. But that's just more empty words.
It doesn't matter what you call it. Your beliefs about what it is are what make it impossible to experience. It doesn't matter if you say it does not exist. It does not, for you at any rate, so you are not only right if you don't believe, you non-belief insured it does not.
Religion is utter garbage. Non-belief is utter garbage. Garbage collectors like to argue whose garbage stinks the most. What does it matter when it's all garbage. We have all been stuffed full of crap. We know absolutely nothing at all. Do you really wonder why you are all ego? Without your ego you would be who you are.
