The possession of knowledge does not kill the sense of wonder and mystery. There is always more mystery.

Cherish that which is within you, and shut off that which is without; for much knowledge is a curse.

An effort made for the happiness of others lifts above ourselves.

It is amazing what you can accomplish if you do not care who gets the credit.

If you do not think about your future, you cannot have one.

Learn from yesterday, live for today, hope for tomorrow. The important thing is not to stop questioning.

Knowledge is love and light and vision.

Your own mind is a sacred enclosure into which nothing harmful can enter except by your permission.

Reading is to the mind what exercise is to the body.

The best preparation for tomorrow is doing your best today.
