It is a natural tendency of the senses to go for sense objects. Every sense has got its raga (like) and dvesha (dislike). You don’t even need intelligence for that. The sense itself is designed for that. The sense becomes attracted or repelled, and then whether you act on it or not has to do with your intelligence. Restraint is done with intelligence, which is very difficult to do because you are not trained for that. But if Bhakti is there, then restraint comes naturally.
