Born at Ekaterinoslav in Southern Russia, Helena Petrovna Blavatsky (née von Hahn) contracted an unconsummated marriage at 17, and spent the next quarter of a century in a variety of adventures, visiting most of Europe, Turkey, Egypt, South America, Mexico, USA, Japan Java and India, and crowning her travels with a trip to Tibet by way of Kashmir and Ladkh. Aware of the world's spiritual dimension since childhood, it was during this latter journey that she underwent her most intense esoteric training, obtaining occult insights and experiences that led to the publication of her magnum opus, the massive and densely argued 'Secret Doctrine'. 'The Key to Theosophy' is a much gentler introduction into the aims and tenets of the society she co-founded to spread knowledge of this 'Divine Wisdom'. The author describes in precise, logical terms the structure of the super-sensible worlds, humanity's spiritual evolution, and the common set of basic principles that lie behind the world's religions. Theosophy considers itself a repository for "the accumulated Wisdom of the ages, tested and verified by generations of Seers..." This book is must-read for all serious occultists and will repay serious study
