The Secret Doctrine, the Synthesis of Science, Religion and Philosophy, a 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.

Blavatsky claimed that its contents had been revealed to her by ‘mahatmas‘ who had retained knowledge of humanity’s spiritual history, knowledge that it was now possible, in part, to reveal.^{[not verified in body]}

Volume one (Cosmogenesis)

The first part of the book explains 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.^[1] These central points are as follows:

1. 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.”
2. 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 in every atom in the Universe, and is the Universe itself.”
3. The third item reiterates the second fundamental proposition (see above), impressing once again that “The Universe is the periodical manifestation of this unknown Absolute Essence.”, while also touching upon the complex Sanskrit ideas of Parabrahmam and Mulaprakriti. This item presents the idea that the One unconditioned and absolute principle is covered over by its veil, Mulaprakriti, that the spiritual essence is forever covered by the material essence.
4. The fourth item is the common eastern idea of Maya. Blavatsky states that the entire universe is called illusion because everything in it is temporary, i.e. has a beginning and an end, and is therefore unreal in comparison to the eternal changelessness of the One Principle.
5. The fifth item reiterates the third fundamental proposition (see above), stating that everything in the universe is conscious, in its own way and on its own plane of perception. Because of this, the Occult Philosophy states that there are no unconscious or blind laws of Nature, that all is governed by consciousness and consciousnesses.
6. The sixth item gives a core idea of theosophical philosophy, that “as above, so below”. This is known as the “law of correspondences”, its basic premise being that everything in the universe is worked and manifested from within outwards, or from the higher to the lower, and that thus the lower, the microcosm, is the copy of the higher, the macrocosm. Just as a human being experiences every action as preceded by an internal impulse of thought, emotion or will, so too the manifested universe is preceded by impulses from divine thought, feeling and will. This item gives rise to the notion of an “almost endless series of hierarchies of sentient beings”, which itself becomes a central idea of many theosophists. The law of correspondences also becomes central to the methodology of many theosophists, as they look for analogous correspondence between various aspects of reality, for instance: the correspondence between the seasons of Earth and the process of a single human life, through birth, growth, adulthood and then decline and death.
