It is our own mental attitude which makes the world what it is for us. Our thoughts make things beautiful, our thoughts make things ugly. The whole world is in our own minds. Learn to see things in the proper light.

Let the mind be cheerful but calm. Never let it run into excesses, because every excess will be followed by a reaction.

He who is alone is happy. Do good to all, like everyone, but do not love anyone. It is a bondage, and bondage brings only misery. Live alone in your mind - that is happiness. To have nobody to care for and never minding who cares for one is the way to be free.

The infinite library of the Universe is in your mind.

The body is mortal and the mind is mortal; both, being compounds, must die.
