As surgeons keep their instruments and knives always at hand for cases requiring immediate treatment, so shouldst thou have thy thoughts ready to understand things divine and human, remembering in thy every act, even the smallest, how close is the bond that unites the two.

Our inward power, when it obeys nature, reacts to events by accommodating itself to what it faces - to what is possible. It needs no specific material. It pursues its own aims as circumstances allow; it turns obstacles into fuel. As a fire overwhelms what would have quenched a lamp. What's thrown on top of the conflagration is absorbed, consumed by it - and makes it burn still higher.

Your days are numbered. Use them to throw open the windows of your soul to the sun. If you do not, the sun will soon set, and you with it.

Imagine you were now dead, or had not lived before his moment. Now view the rest of your life as a bonus.

The most complete revenge is not to imitate the aggressor.

Everything is in a state of metamorphosis. Thou thyself art in everlasting change and in corruption to correspond; so is the whole universe.

Whoever values peace of mind and the health of the soul will live the best of all possible lives.
