The remarkable feature of the brain appears to be the physiological basis for the possibility of transforming our minds. By mobilizing our thoughts and practicing new ways of thinking, we can reshape our nerve cells and change the way our brains work. It is also the basis for the idea that inner transformation begins with learning (new input) and involves the discipline of gradually replacing our “negative conditioning” (corresponding with our present characteristic nerve cell activation patterns) with “positive conditioning” (forming new neural circuits). Thus, the idea of training the mind for happiness becomes a very real possibility. (Dalai Lama)
