The ideal of faith in ourselves is of the greatest help to us. If faith in ourselves had been more extensively taught and practiced, I am sure a very large portion of the evils and miseries that we have would have vanished. Throughout the history of mankind, if any motive power has been more potent than another in the lives of all great men and women, it is that of faith in themselves.
Swami VivekanandaStrength, strength is what the Upanishads speak to me from every page. This is the one great thing to remember, it has been the one great lesson I have been taught in my life; strength, it says, strength, O man, be not weak. Are there no human weaknesses? - says man. There are, say the Upanishads, but will more weakness heal them, would you try to wash dirt with dirt? Will sin cure sin, weakness cure weakness? Strength, O man, strength, say the Upanishads, stand up and be strong.
Swami VivekanandaWhat do we call the river? Every moment the water is changing, the shore is changing, every moment the environment is changing, what is the river then? It is the name of this series of changes.
Swami VivekanandaWhat makes a man stand up and work? Strength. Strength is goodness, weakness is sin.
