If you do not possess the staff of caution and discrimination, use the eyes of him who sees. If there is no staff of caution and discrimination, do not wander on the road without a guide.
RumiThe ear participates, and helps arrange marriages; the eye has already made love with what it sees. The eye knows pleasure, delights in the body's shape: the ear hears words that talk about all this. When hearing takes place, character areas change; but when you see, inner areas change. If all you know about fire is what you have heard see if the fire will agree to cook you! Certain energies come only when you burn. If you long for belief, sit down in the fire! When the ear receives subtly; it turns into an eye. But if words do not reach the ear in the chest, nothing happens.
Rumi
