That which makes you miserable is the only sin. That which takes you away from yourself is the only thing to be avoided.
While one is asleep one cannot do anything that is good. Virtue is impossible in unconsciousness, only sin is possible. Unconsciousness is the source of sin.
If you are unconscious, unaware, you are living only in the body, the mortal. And a person who lives for the body, in the body, and only for the body, lives in sin.
If you live with alertness, you live rightly. If you live in imitation, you live wrongly. To me there is only one sin: And that is not to be yourself. And to me there is only one virtue: And that is to know yourself.
