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.
