All animals - not only prehistoric animals, dinosaurs, brontosaurus, mammoths, etc - are present in man's subconscious by their astral body
"In a human being, the subconscious is made up of regions filled with prehistoric animals, dinosaurs, brontosaurus, mammoths, etc., and when psychoanalysts explore the subconscious, they are seldom aware of these dangerous regions they are stirring up. All these monsters are there alive! You might say, 'How can they be alive? They have disappeared a long time ago!' They have disappeared from the face of the earth, but they still live in man as instincts and desires. The fact that their bodies do not exist physically anymore does not mean that their astral body does not exist: it does! All animals - not only prehistoric animals - are present in man's subconscious by their astral body. That is why the psychoanalysts who are not taught by initiatic science, and who carelessly dare to stir up the layers of the subconscious, on the pretext of searching for the origin of certain troubles, often succeed only in waking up these animals. I am not saying that psychoanalysis is necessarily dangerous, but it must be practiced by people who are themselves psychologically very strong and very experienced, and who will not let their patients be eaten up by their inner monsters"
