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).
Why not simply honor your parents, love your children, help your brothers and sisters, be faithful to your friends, care for your mate with devotion, complete your work cooperatively and joyfully, assume responsibility for problems, practice virtue without first demanding it of others, understand the highest truths yet retain an ordinary manner? That would be true clarity, true simplicity, true mastery.
If you wish to become a divine immortal angel, then restore the angelic qualities of your being through virtue and service. This is the only way to gain the attention of the immortals... These angelic teachers cannot be sought out; it is they who seek out the student. When you succeed in connecting your energy with the divine realm through high awareness and the practice of undiscriminating virtue, the transmission of the ultimate subtle truths will follow.
Do nondoing, strive for non-stiving, savor the flavourless, make much of little, repay enmity with virture; plan for difficulty when it is still easy, do the great while it is still small.
He who has achieved this state Is unconcerned with friends and enemies, With good and harm, with honor and disgrace. This therefore is the highest state of man.
