Now coming to the question: how can this magnetism be developed? This magnetism is developed by study, by concentration, by a keen observation of life, and by the knowledge of repose. Very many intelligent persons without knowing how to concentrate and how to take repose in their lives, in time blunt their intelligence; because there is a certain fund of energy which is reserved and which is limited, and when there is too much pressure put upon that limited energy, in the end what happens? A person becomes less and less intelligent, and his power of mind will decrease every day. And whenever you will find a most intelligent man becoming every day more dull, that always proves that the amount of energy that has been there has been spent.
