The more you learn self-honesty, the deeper can the truth penetrate into the core of the soul. But it takes a lot of doing before the core is reached. Wherever the conscious emotions, opinions, thoughts, conclusions, and desires are separated from those which are unconscious, we can see a wall in the human soul. You all know that thoughts and feelings create forms of subtle matter which are of a substance every bit as real as your material substance. So this wall is a reality and, alas, often a greater reality than your matter.
