Surrender does not mean give up it means let go. Let go of what does not serve you. Take a look at things in your life, in your body, in your mind that do not move you in a positive direction. Then surrender to them. In yoga we use the term surrender to the higher self. Let go of the ego. When we surrender to this higher self we begin cultivating a deep and trusting relationship with the universe, and making each of our actions an offering to something bigger than us.
-Trust. The. Universe.
