The Rule of St. Benedict - Chapter 7. Humility

(10) The first step of humility, then, is that a man keeps the, "fear of God," always, "before his eyes," (Ps 35[36]:2) and never forgets it.
(11) He must constantly remember everything God has commanded, keeping in mind that all who despise God will burn in hell for their sins, and all who fear God have everlasting life awaiting them.
(12) While he guards himself at every moment from sins and vices of thought or tongue, of hand or foot, of self-will or bodily desire,
(13) let him recall that he is always seen by God in heaven, that his actions everywhere are in God’s sight and are reported by angels at every hour.
