Education is not the amount of information that is put into your brain and runs riot there, undigested, all your life. We must have life-building, man-making, character-making assimilation of ideas. If you have assimilated five ideas and made them your your life and character, you have more education than any man who has got by heart a whole library.
Every idea that strengthens you must be taken up and every thought that weakens you must be rejected.
The powers of the mind are like rays of light dissipated; when they are concentrated, they illumine. This is our only means of knowledge.. How has all the knowledge in the world been gained but by concentration of the powers of mind? The world is ready to give up its secrets if we only know how to knock, how to give it the necessary blow. The strength and force of the blow come through concentration. There is no limit to the powers of the human mind. The more concentrated it is, the more power is brought to bear on one point; that is the secret.
