There are hundreds of thousands of microbes surrounding us, but they cannot harm us unless we become weak, until the body is ready and predisposed to receive them. There may be a million microbes of misery floating about us. Never mind! They dare not approach us, they have no power to get a hold on us, until the mind is weakened. This is the great fact: strength is life. Weakness is death. Strength is felicity, life eternal, immortal. Weakness is constant strain and misery: weakness is death
Swami VivekanandaBy doing well the duty which is nearest to us, the duty which is in our hands now, we make ourselves stronger; and improving our strength in this manner step by step, we may reach a state in which it shall be our privilege to do the most coveted and honored duties in life and in society.
Swami Vivekananda
