“He said, “That which proceeds out of the man, that defiles the man. For from within, out of the hearts of men, proceed evil thoughts, adulteries, sexual sins, murders, thefts, covetings, wickedness, deceit, lustful desires, an evil eye, blasphemy, pride, and foolishness. All these evil things come from within and defile the man.” -Mark 7:20–23 

“Withdraw from what feeds the passions, and they will weaken.” - Abba Moses
