The Psychology of Kundalini Yoga: Notes of the Seminar Given in 1932 - C.G. Jung

"Kundalini yoga presented Jung with a model of something that was almost completely lacking in Western psychology, an account of the development phases of higher consciousness... Jung's insistence on the psychogenic and symbolic significance of such states is even more timely now than then. As R. D. Laing stated... It was Jung who broke the ground here, but few followed him ." - From the introduction by Sonu Shamdasani
