"May the Lord Jesus, Who said: 'Ask, and ye shall receive' (John 16:24), grant all your requests. Only prepare your house, and sweep it thoroughly to receive the Divine gifts. They remain secure only where there is no impurity. He who tastes of them becomes a stranger to the old Adam; he becomes crucified to the world as the world is to him, and lives always in the Lord."
St. Barsanuphius and St. John
