The body cannot be cured without regard for the soul.

Do not do to others what angers you if done to you by others.

Those then who know not wisdom and virtue, and are always busy with gluttony and sensuality, go down and up again as far as the mean; and in this region they move at random throughout life, but they never pass into the true upper world; thither they neither look, nor do they ever find their way, neither are they truly filled with true being, nor do they ever taste of pure and abiding pleasure.

I was afraid that by observing objects with my eyes and trying to comprehend them with each of my other senses I might blind my soul altogether.

To know thyself is the beginning of wisdom.

It is not living that matters, but living rightly.
