About the book (from Goodreads):
In the present book, Ouspensky analyzes certain older schools of thought, of both East and West, connects them with modern ideas and explains them in the light of twentieth-century discovery and speculations in physics and philosophy. In the process he explores relativity, the fourth dimension, Christian symbolism, the tarot, yoga, dreams, hypnotism, eternal recurrence, and various psychological theories.
The book closes with an examination of the role of sex in the evolution of man toward superman. Anyone interested in the occult, mysticism and the relationship of those elements to scientific developments in the modern world will find much to ponder in these stimulating, thought-provoking pages.
