I suggest prerequisite readings to anyone who really wants to get the most out of this extremely well written book. You need to understand the basics of quantum mechanics. For that, first read Gary Zukav's masterpiece "The Dancing Wu Li Masters" followed by Fritov Capra's "The Tao of Physics." The latter covers the same basic principles but from a perspective that adds to overall understanding. Follow these with Amit Goswami's masterpiece, "Physics of the Soul." All three books are written for laypeople. You really need to understand quantum physics for yourself to believe it's incredible implications which McTaggert discusses so well. On the other hand, if you read "The Field" with no understanding of QP, you might not appreciate how very "real" are the amazing things discussed in this book. Castaneda fans will instantly realize that Carlos "knew" regardless of whether or not Don Juan was real.
