Albert Schutz introduces the results of over fifty years of investigation in Europe, the Middle East, and South America. He argues that the ancient religious artwork provide the key to systematic development of the full potential of the mind. His surprising thesis is that positions of the hands shown in much religious art provide the mcan to properly direct the mind during meditation. Evidence for the system he describes is gathered from the religious writings of many cultures, including the oral tradition of the Bektashi Sufis. However, the proof of his argument was established by experiments. This book provides the basic information for such experiments.
