You think because you understand 'one' you must also understand 'two', because one and one make two. But you must also understand 'and'.
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.
RumiDo you think I know what I'm doing? That for one breath or half-breath I belong to myself? As much as a pen knows what it's writing, or the ball can guess where it's going next.
Rumi
