I think most religion is about control over people, in order for a religion to survive, it has to have things that lure you in and once in to keep you there. They use such terms as salvation, god's wrath, sinner, free gift, everlasting life, everlasting torment, as control devices so that the religion can survive, gain wealth.
Religion is putting your faith in the founders of that religion, trusting that they know what they are talking about.
A religion that doesn't try to control people will not get very far for very long.
Spirituality in my estimation is the turning inward, (I don't think of it as outwardly manifested by following a path written by some ancient holly book of some vengefull god like jehovah.) We all do it to some degree or other, regulated to some degree by our previous religous indoctrination.
I see religion also as capitalizing on man's need to know. Man before modern science, put gods everywhere, god is in the thunder, the hale, the sea, the sun, the moon(the bible is no exception). They had no idea the earth was round, then came the teliscope and things start to change.
Quite naturally we invented answers to our questions we have been doing this ever since we have been thinking with words, we are still doing it. Today's truth may be tomorrows myth.
