The lectures here presented were delivered in New York during the past winter. The purpose of this series was to present to their auditors the testimony of science as to the relation of matter and of consciousness; to enable the hearers to observe the identical manifestation of these relations and of certain basic laws in successively higher states of being, and thus to bring to them a realization of the universality of the evolutionary process and its actuality; and to deal somewhat with the nature of the expanded states of consciousness and the enlarged life toward which all mankind is travelling. They thus were intended to serve as an introduction to the more detailed study and application of the laws of life and human unfoldment generally included in the term of "occultism.".
