Helena Petrovna Blavatsky

Founder of the Theosophical Society and writer of the immense and hugely influential "The Secret Doctrine" (1888), which even Einstein kept on his desk.

"I discovered, with mystical astonishment, an inexhaustible spring of divine wisdom in the wonderful pages of The Secret Doctrine, an extraordinary work of the venerable, great Master Helena Petrovna Blavatsky, a sublime martyr of the nineteenth century." -Samael Aun Weor, The Three Mountains
