Among men we see that some are like the rock, others like the plant or like the animal and some have the human quality. The man who is like a rock has not much expression; he has no magnetism. He has only that which is in his appearance, just like the stones have, the emerald, the ruby; when that appearance is gone nothing is left. The man who is like a plant has no intelligence, only some feeling, some personality. Either is there some fragrance of the personality, some beauty, or he is like a thorn, or there is poison. When man is like an animal he has feelings, passions, but he cannot give them expression. Only that man is a human being who has the gift of expression, who speaks out what he feels.
