As you read this material, I would ask that you keep an open mind before you draw your conclusions about your beliefs and in doing so you will have a better understanding of the three. I can assure you there are as many manuals, books and theories on all these subject matters and each one claiming to be right and the rest all wrong. But if you think logically on this material you will at least have a view that I believe makes "Common Sense", which in turn may help you answer the questions of life and why you are here and what is your purpose.
