Jerry Pinto said this quote

Love is never enough. Madness is enough. It is complete, sufficient unto itself. You can only stand outside it as a woman might stand outside a prison in which her lover is locked up. From time to time, a well-loved face will peer out and love floods back. A scrap of cloth flutters and it becomes a sign and a code and a message and all that you want it to be. Then it vanishes and you are outside the dark tower again.
