It is the author's thesis that all life's problems arise from three illusions which were dawn over mankind at the beginning of history when the Solar Deity seeking to manifest drew over himself three illusions  giving rise to three primary illusions of Space or objects existing in space as dimensions, Time as succession of events and Self as separated existence. 

The mind of man vainly tries to measure Boundless space dimensionally, Eternity in terms of our terrestrial time and fails to conceive Self except in terms of separate existence. Grasp of Infinity, Eternity and Unity appear to elude its grasp.

The author has sought to bring all the Theosophical Wisdom relating to Matter and Cosmogenesis, Involution and Evolution and the laws governing these under the three sections Illusions of Space, Time and Self. He contends that Science, Philosophy and Religion are the means for grappling with these illusions. 

The book with many illustrations and charts is very instructive and illuminating.
