Extract from a letter of the St. Bernhard of Clairvaux to Papst Eugene III (12.century)
Take care of yourself !
"It is not the virtue of patience to permit yourself to be enslaved when you can be free ... Are you less a slave because you serve not one but all? I praise your devotion to humanity, but only if it be complete. Now, how can it be complete when you have excluded yourself? You too are human ... You also should drink from the waters of your well ... If you are a stranger to yourself, to whom are you not? If a man is no use to himself, to whom is he useful?"
