“A person’s body is like a walled city, which has five gates.  One gate is the eyes, one the ears, one the nose, one the mouth, one the arms and legs. Every type of evil or good comes and goes through these gates.  The soul is the resident of this city, a person’s good works are its jewels and treasure. The mind is the king and keeper of this treasure.  Satan and his spirits are the evil will which occupies the city and steals the treasure which is the souls goodness…Wise is the man who guards his ears with the word of God, eyes from evil sights, tongue from evil words, hands from evil works and feet from staying off the path—who uses his tongue for good words, hands for works of charity and is diligent in prayer. In this way, our city is defended and our treasure is safe from enemies.” – Hovhannes Erznkatsi, Letter to the Princes of the Canton of Yekeghik (13th century)
