It is the calm, forgiving, equable, well-balanced mind that does the greatest amount of work.

The brain can be developed just as the muscles can be, if one will only take the pains to train the mind to think.

The mind is everything. What you think you become.

We can't build our dreams on suspicious minds.

A disciplined mind leads to happiness, and an undisciplined mind leads to suffering.

A positive state of mind is not merely good for you, it benefits everyone with whom you come into contact, literally changing the world.
