This book records the results of certain clairvoyant investigations carried out by Mr Geoffrey Hodson on the effects produced by music upon the adjacent matter of the superphysical worlds. Eight compositions, including Handel, Bach, Mozart, Haydn and Wagner were studied and the results are recorded here in words and colour. Mr Hodson’s observations arising from his clairvoyant research were carefully taken down while each performance was proceeding, and to these descriptions pictures were produced by artists later. The music was under the guidance of Dr Gordon Kingsley, of Beverly Hills Church, in Hollywood, California, and he has provided notes on the compositions. Also included is a study of the responses of physical substances to various vibrations, carried out by the Swiss scientist and artist Dr Hans Jenny, published here by permission of the author and the Editor of THE UNESCO COURIER, 1969, in which it appeared. This book is an imprint of the Theosophical Publishing House, Adyar, and is imported from India.
