When we practice yoga, we start to pull out all those negative spaces that we hold onto in our body. If we push ourselves out of our comfort zone- fear comes up, doubt surfaces, anger rises, frustration emerges and righteousness takes over. By practicing yoga and pushing ourselves beyond our edge, we can start to get into these "stuck" places in our bodies. Through the kriyas (asanas) and pranayama (breath) are we able to surrender and let these negative emotions go.
