Franz Hartmann was a German medical doctor, theosophist, freemason, occultist, geomancer, astrologer, and prolific esoteric author. Here he writes about the Self. He who refuses to seek for the light within himself will not find the true light anywhere in externals, and will continue to dwell in his darkness. He who finds truth within himself will also recognize the spirit of truth throughout all nature; for it is the spirit of truth in him who recognizes itself in everything.
