Be strong — not merely a physical strength of a bull, but the subtle vitality of a calm mind, diligent in its application, consistent in its logical thinking, replete with a will to win over all negative tendencies that poison and weaken the mind. In fact, a strong mind is seriously cultivated by living moral values.
Never yield readily to the endless demands of the body; never come under the irresistible charms of the sensuous objects around you. If your intellect is not alert, your mind will run out seeking some immediate pleasure by hugging some object of false magic in the outer world.
