Understand this if nothing else: spiritual freedom and oneness with the Tao are not randomly bestowed gifts, but the rewards of conscious self-transformation and self-evolution.
To know how little one knows is to have genuine knowledge. Not to know how little one knows is to be deluded. Only those who know when they are deluded can free themselves from such delusion. The intelligent people are not deluded, because they know and accept their ignorance as ignorance, and thereby have genuine knowledge.
The universe is deathless; Is deathless because, having no finite self, it stays infinite. A sound man by not advancing himself stays the further ahead of himself, By not confining himself to himself sustains himself outside himself: By never being an end in himself he endlessly becomes himself.
Clay is molded to form a cup, But it is on its non-being that the utility of the cup depends. Doors and windows are cut out to make a room, But it is on its non-being that the utility of the room depends. Therefore turn being into advantage, and turn non-being into utility.
If you understand others you are smart.
If you understand yourself you are illuminated.
If you overcome others you are powerful.
If you overcome yourself you have strength.
If you know how to be satisfied you are rich.
If you can act with vigor, you have a will.
If you don't lose your objectives you can be long-lasting.
If you die without loss, you are eternal.
