Weep over your sin
Weep over your sin: it is a spiritual ailment; it is death to your immortal soul; it deserves ceaseless, unending weeping and crying; let all tears flow for it, and sighing come forth without ceasing from the depths of your heart.
In profound humility I weep for all my sins, voluntary and involuntary, conscious and unconscious, covert and overt, great and little, committed by word and deed, in thought and intention, day and night, at every hour and minute of my life.
- St. Basil the Great
