The Challenge of the Mind: An Essential Guide to Buddha's Teachings: Zen, Karma, and Enlightenment

I have read just about everything from Tibetan,Chinese, & Japanese Buddhism to Zen to Taoism to the Bible to Greek Philosophers to metaphysical new age to many other more obscure material for more than 16 years. I must say this book is very straightforward but I could see how some people might not agree with everything the author has to say. I think this is the best book on the subject of Karma because of it's deceptively simple manner of writing which makes it easy to understand given that you're smarter than the average bear.
