In the Sufi literature, which is known to the world as the Persian literature, there is much talk about the "curls of the Beloved," and many have often wondered what it means. The curl is a symbol of something which is curved and round. The curve denotes the twist in the thought of wisdom. Very often a straight word of truth hits upon the head harder than a hammer. That shows that truth alone is not sufficient, the truth must be made into wisdom. And what is wisdom? Wisdom is the twisted truth. As raw food cannot be digested, and therefore it is cooked, although raw food is more natural than cooked food, so the straight truth is more natural, but is not digestible, it needs to be made into wisdom.
