Most people have, at some time in their lifetime, asked themselves: Why me? What is life all about? What is the meaning and purpose of life? Why are we here? Why do we need to be here? And many other similar questions. To date, I am not aware of any authority, religious or scientific; that has given an adequate and meaningful answer to these questions. In reality, the answers lie in spirit evolution, in each individual's spiritual development, and in reincarnation. For too long populations have lived in ignorance of true spiritual facts and relied on the words of those with limited spiritual knowledge. This has led to them being indoctrinated and controlled by superstition and religious doctrines. The purpose of this book is to convey in simple layman's language the basic truths concerning the interrelationship between the human spirit and the physical body, and to introduce other related subjects. I would like to think that what you read will trigger a need for you to investigate further the facts for yourself, so that you can reach your own conclusions.
