A man receives a telegram that his only son died of Pneumonia. At once his face becomes pale; his mind is agitated; he turns nervous; he has no appetite; his red corpuscles are destroyed. If you reflect over this sequence of the whole trouble, you will find that the mind was the first thing to be affected; he received a mental shock and afterwards the entire mechanism of the body reacted to it. This is an instance which should eloquently convince of the influence that the mind exerts on the body. Psychologists are of the opinion that disease is not primarily of the body or of the flesh but of the mind. It is true that disease is caused by the effects on the human system caused by the poisons generated in the blood by anger, revenge, hatred, lust and greed.
