The fourth (of the four cardinal virtues) is supportiveness: this manifests as service to others without expectation of reward. (Paraphrased: Such service is not a mere conforming to some external rule of behavior, but instead a manifestation of your original nature).

The Tao never acts with force, yet there is nothing that it can not do.

Knowing others is to be clever. Knowing yourself is to be enlightened. Overcoming others requires force. Overcoming yourself requires strength.

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.

If you tell me, I will listen. If you show me, I will see. If you let me experience, I will learn!

To know and not to do is not yet to know.

Cultivate virtue in the world, and it will be universal.
