The powers of the mind are like the rays of the sun when they are concentrated they illumine.
They alone live, who live for others.
As soon as we identify ourselves with the work we do, we feel miserable; but if we do not identify ourselves with it, we do not feel that misery.
The world is the great gymnasium where we come to make ourselves strong.
The benefits of knowledge can only be realized in practice.
We came to enjoy; we are being enjoyed. We came to rule; we are being ruled. We came to work; we are being worked. All the time, we find that. And this comes into every detail of our life.
