Orage had met P. D. Ouspensky for the first time in 1914. Ouspensky's ideas had left a lasting impression and when he moved to London in 1921 Orage began attending his lectures on "Fragments of an Unknown Teaching", the basis of his book "In Search of the Miraculous". From this time onwards Orage became less and less interested in literature and art, and instead focused most of his attention on mysticism. His correspondence with Harry Houdini on this subject moved him to explore ideas of the afterlife. He returned to the idea that there are absolute truths and concluded that they are embodied in the "Mahabharata".
