You who desire for yourself purity whereby the Lord of all may be seen, do not slander nor listen to words of calumny concerning your brethren. If a quarrel is going on near you or if you hear angry words, stop up your words and flee, lest your soul perish. The soul of an irascible man is devoid of the mysteries of God, but any one who is innocent and peaceable is a fount of the mysteries of the New World. Indeed Heaven is already inside you if you are pure, and there you see angels rejoicing and their Lord with them and within them.

[John of Dalyatha, Discourse 3]
