Young men who still feel strongly the urge for physical love and pleasure and yet who also want to take on the regime of a monastery must discipline themselves with every form of vigilance and prayer, avoiding all dangerous comfort, so that their last state may not be worse than their first. For those sailing the tides of spirituality know only too well that the religious life can be a harbor of salvation or a haven of destruction, and a pitiable sight indeed is the shipwreck in port of someone who had safely mastered the ocean.

—St. John Climacus
