Use any mood to meditate. Then you have forgotten the other completely, and you are not suppressing anything. You are just moving down with some energy which has come up. Every energy comes from the source, so right now the path is warm and you can use that path to go back. And the moment you reach to the original source, the energy will subside into the original source. It is not suppression: the energy has gone back to the original source. And when you become capable of reuniting your energy with your original source, you have become the master of your body, your mind, your energy. You have become the master. Now you will not dissipate your energy.
