There is an old illusion. It is called good and evil.

My brother, are war and battle evil? Necessary, however, is the evil; necessary are the envy and the distrust and the back-biting among the virtues.

The rain could turn to gold and still your thirst would not be slaked. Desire is unquenchable or it ends in tears, even in heaven.

By oneself the evil is done, and it is oneself who suffers: by oneself the evil is not done, and by one's Self one becomes pure. The pure and the impure come from oneself: no man can purify another.

The only good is knowledge and the only evil is ignorance.

The struggle with evil by means of violence is the same as an attempt to stop a cloud, in order that there may be no rain.
