A saint is a person who practices the keystone human virtue of humility. Humility in the face of wealth and plenty, humility in the face of hatred and violence, humility in the face of strength, humility in the face of your own genius or lack of it, humility in the face of another's humility, humility in the face of love and beauty, humility in the face of pain and death. Saints are driven to humbling themselves before all the splendor and horror of the world because they perceive there to be something divine in it pulsing and alive beneath the hard dead surface of material things -- greater and purer than they are.
The essential self is fundamentally invulnerable and at ease, because it is anchored in Being. This anchoring at the core of oneself allows the personality to be much more vulnerable, open, honest. If the essential self adopts a provisional or social identity — which may be necessary for certain reasons—it does not take it too seriously, does not become completely identified with it. The essential self does not become inflated with its identity, it lives in the humility of presence and can keep a sense of humor about itself.
