Six lectures given by Annie Besant in 1904. Subjects include: The Larger Consciousness; The Mechanism of Consciousness; Sub-Consciousness and Super-­Consciousness; Clairvoyance and Clairaudience; Telepathy; and Methods of Unfoldment."Psychology has travelled far during the last forty years: Some forty years ago it was accepted on almost all sides of the scientific world that, in order to follow safely psychological studies, you must base your psychology on physiology. Now there is a truth in that, which I do not want to overlook; that you cannot deal accurately and fully with consciousness without knowing some thing of the nature of its instruments."
