Like the bee, we distill poison from honey for our self-defense--what happens to the bee if it uses its sting is well known.

Do not look back and do not dream about the future. It will neither give you back the past, nor satisfy your other daydreams. Your duty, your reward, your destiny, is in the present moment

To reach perfection, we must all pass, one by one, through the death of self-effacement.

A task becomes a duty from the moment you suspect it to be an essential part of that integrity which alone entitles a man to assume responsibility.

There is a point at which everything becomes simple and there is no longer any question of choice, because all you have staked will be lost if you look back. Life's point of no return.

The longest journey is the journey inward.

It is more important to understand the ground of your own behavior than to understand the motives of another.
