There are many people who are looking for practical instructions in Occultism. It becomes necessary, therefore, to state once and for all: a) The essential difference between theoretical and practical Occultism; or what is generally known as Theosophy on the one hand, and Occult science on the other, and: b) The nature of the difficulties involved in the study of the latter. This book is an imprint of the Theosophical Publishing House, Adyar, and is imported from India.
