The Secret Doctrine, the Synthesis of Science, Religion and Philosophy, is a pseudo-scientific esoteric book originally published as two volumes in 1888 written by Helena Blavatsky. The first volume is named Cosmogenesis, the second Anthropogenesis. It was an influential example of the revival of interest in esoteric and occult ideas in the modern age, in particular because of its claim to reconcile ancient eastern wisdom with modern science. Proponents widely claim the literature contains clues as to how the nature of prayer was 'covered' and expunged from common wisdom, except for those with a keen-eye. The book has been criticized for promoting pseudoscientific concepts and for borrowing those from other systems. Volume one (Cosmogenesis) In Volume One, Blavatsky details her interpretation of the origin and evolution of the universe itself, in terms derived from the Hindu concept of cyclical development. The world and everything in it is said to alternate between periods of activity (manvantaras) and periods of passivity (pralayas). Each manvantara lasts many millions of years and consists of a number of Yugas, in accordance with Hindu cosmology. Blavatsky attempted to demonstrate that the discoveries of "materialist" science had been anticipated in the writings of ancient sages and that materialism would be proven wrong. Cosmic evolution: Items of cosmogony In this recapitulation of The Secret Doctrine, Blavatsky gave a summary of the central points of her system of cosmogony. These central points are as follows: The first item reiterates Blavatsky's position that The Secret Doctrine represents the "accumulated Wisdom of the Ages", a system of thought that "is the uninterrupted record covering thousands of generations of Seers whose respective experiences were made to test and to verify the traditions passed orally by one early race to another, of the teachings of higher and exalted beings, who watched over the childhood of Humanity." The second item reiterates the first fundamental proposition (see above), calling the one principle "the fundamental law in that system [of cosmogony]". Here Blavatsky says of this principle that it is "the One homogeneous divine Substance-Principle, the one radical cause. … It is called "Substance-Principle," for it becomes "substance" on the plane of the manifested Universe, an illusion, while it remains a "principle" in the beginningless and endless abstract, visible and invisible Space. It is the omnipresent Reality: impersonal, because it contains all and everything. Its impersonality is the fundamental conception of the System. It is latent
