I have a portrait of St. Francis de Sales! He’s on the opposite side of the desk. I’m a Catholic but love the little images from Hinduism. I’m looking for a comparative religion course in my area. It used to be taught at high school and college level but I don’t see it much anymore.
If you do not already have one, the Huston Smith book on the world religions is excellent for an overview of the major world religions. Very worthwhile.
Wikipedia can make you an instant expert. On non-political subjects, it’s awesome.
