This book, as all things, came into being because of a thought acted upon. Neville left us October 1, 1972 and, since that time, I have invested many hours transcribing the hundreds of tapes I have of his lectures. Neville explained that the ark of life contained and could be understood on three levels: the literal, psychological and spiritual. The lectures which are available deal mainly with the spiritual. However, because those who are now hearing his words on tapes and reading his lectures, did not hear him speak on the second (or psychological) level, I realized the need to provide that psychological plane as a foundation for the higher, spiritual level. And so, the thought was planted in my mind. What if there were some lectures that taught this principle on a practical level? Wouldn't it be wonderful if such a series could be found and made available for those who would desire it. And then one day I received a letter from a lovely lady in San Francisco who said she was moving into a retirement home and wanted to send me some notes she had from Neville's lecture series in San Francisco in 1952. These notes constitute this book.
