Love with wisdom is bliss. Love without knowledge or wisdom is pain. Why is there pain in love? That is what you are wondering or questioning about! It is not love which is giving you pain. If it is just purely love, that means you just care for someone, you want the best for them, and then there is no pain. But when you want something in return from them or you have demands from them, then there is pain. +Sri Sri Ravi Shankar
