i would like to think that religion is the opium of the masses, i am a marxist at heart, but i also think that the masses created that opium long before they were the subject of control by the bourgeosie. religion is a useful tool for controlling masses, but that can't be it's source and does not explain how so many people find real comfort in religion that goes way beyond mere guidance. however, i do have a problem with the blind leap of faith i would have to make to believe in heaven / hell / devil / god, it's probably human nature to group together happy and unhappy events, to attribute them to one thing rather than another, maybe to give that thing a personality, it makes sense, it's just not a leap i can make. All that and many years studying phiosophy has lead me to buddhism, i would desribe myself as a religious person these days. I've studied many religions and cannot find any that is not based on compassion for our fellow man, if all of us, religious or not, were to prioritise that, i would be able to belive in heaven, i'd be there.
