How the Great Religions Began
Like it or not statistics say that 96% of humanity consider themselves religious. A huge percentage of them subscribe to a handful of faiths, buddhism, confucianism, taoism, judaism, islam and christianity. If you would like to understand the mind of humanity, what drives it in so much of its day, I'm not sure you can do so without at least a basic understanding of the religions which they follow. If you would understand the world, you should read a book like this, in fact this one is pretty good even if Amazon doesn't have a picture for it, so perhaps read this one.
