Some people will assign terms such as spiritualism, black magic or clairvoyance to the realm of the supernatural. Others will deny their very existence and dismiss them as mere figments. However, these issues are neither supernatural nor pure fantasies. Reiner Niessen, one of the few remaining Zen masters in this world, unveils the logical explicability of such phenomena in his book “Bios Logos – The Doctrine of Life” (available as ebook from Amazon). If this posting is called "spam", I am sorry. I just think, this book can be very interesting for this forum. In any other case - the author of the book is ready to discuss with you about the book and theses and logical experiments from the book.
