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).
LaoziWhen the palace is magnificent, the fields are filled with weeds, and the granaries are empty.
LaoziArms are instruments of ill omen.... When one is compelled to use them, it is best to do so without relish. There is no glory in victory, and to glorify it despite this is to exult in the killing of men.... When great numbers of people are killed, one should weep over them with sorrow. When victorious in war, one should observe mourning rites.
Laozi
