Ukrainian-born Madame Helena Blavatsky (1831-1891) was a co-founder of the theosophy movement in the United States, which she later extended to Europe and India, though her later years were dogged by ill health and controversy. In this book, published in 1886, A. P. Sinnett (1840-1921), a fellow theosophist and writer, sets out a defence of Blavatsky, writing that ‘I have reason to believe that the attempt will respond to the wishes of a great many people … who regard the current aspersion on Mme. Blavatsky’s character with profound indignation’. He outlines the many extraordinary events in her life, covering her childhood in Russia and claims to an early connection with the supernatural world, her brief unhappy marriage and decade of extensive global travels, her time of study in India, and the criticism she received about some of her ‘phenomena’ and practices.
