A person whose sense of discrimination and feeling is well developed may find that a visitor coming into the house brings with him a certain influence: good feeling or bad feeling, an irritable feeling or a blissful feeling. There is something with him besides his knowledge, besides his beauty; when he leaves the house his body leaves, and together with it his strength and beauty, all that is material in him; yet there is something left in that room for a certain time after he has gone. The whole atmosphere is charged and we feel that there is something left there. The more keenly we watch life, the more wonderful it is. All the miracles and phenomena are before us; our everyday life is a miracle. If we are only absorbed in things which are material and not in things of a delicate character, we do not see this because we blunt our sensitivity. It is then that we think that what we do not see or perceive does not exist. Consider, for instance, how infectious yawning is. This shows we can never say there is nothing beyond what the eyes and flesh can see.
