A clear mind can have a clear thought, and therefore clearness of thought depends upon the cleanliness and the awakening of the centers. When the organs of the body, and especially the centers, are not in a clean and normal condition, then one's own thought is unclear to oneself, and the thought of others still less clear. Man in reality is by nature a mind-reader, and the state of body and mind is abnormal when he cannot read thought. To one to whom his own thought is clear, the thought of another person will be clear also.
