In this formative study, Georg Kühlewind establishes a truly spiritual psychology. This psychology distinguishes between the subconscious regions explored by previous psychological schools and the supra-consciousness, which is identified as the light-filled, living source of our normal waking awareness and thought. As such, it is radically "present," in contrast to our normal thoughts and emotions, which belong to a "past-consciousness," composed of pre-formed elements. The principle of higher cognition guides Kühlewind's presentation, as it guides the individual psyche, to a place in which human and world are no longer separate.

Kühlewind shows, and the attentive reader can experience, that the non-dual realm is not to be found spatially or temporally, but exists within the processes of cognition. From this it becomes clear how the diseases of consciousness so familiar to us today arise from the decay of this higher cognitive potential. Special chapters on memory and on the subconsciousness offer specific results of Kühlewind's own spiritual scientific researches. The book also includes new indications about the meditative path--the steps by which our current cognitive powers can be developed in the direction of their spiritual source.
