Real love is wisdom. What most people think of as love is just an impermanent feeling. If you have a nice taste every day, you will soon get tired of it. In the same way, such love eventually turns into hatred and sorrow. Such worldly happiness involves clinging and is always tied up with suffering, which comes like the policeman following the thief.
Nevertheless, we cannot suppress nor forbid such feelings. We just should not cling to or identify with them but should know them for what they are. Then Dharma is present. One loves another, yet eventually the beloved leaves or dies. To lament and think longingly, grasping after that which has changed, is suffering, not love. When we are at one with this truth and no longer need or desire, wisdom and the real love that transcends desire fill our world. ~Ajahn Chah
