As the gradual pouring of water on a fire completely extinguishes the flame, so the tears of true mourning [for sinfulness] are able to quench every flame of anger and irritability.

St. John Climacus

My friends, God does not ask or desire that man should mourn from sorrow of heart, but rather that, out of love for Him, he should rejoice with spiritual laughter. Remove the sin, and the tear of sorrow is superfluous for your eyes.

St. John Climacus
