"Karma is often wrongly confused with the notion of a fixed destiny. It is more like an accumulation of tendencies that can lock us into particular behavior patterns, which themselves result in further accumulations of tendencies of a similar nature....But it is not necessary to be a prisoner of old karma....Here's how mindfulness changes karma. When you sit, you are not allowing your impulses to translate into action. For the time being, at least, you are just watching them. Looking at them, you quickly see that all impulses in the mind arise and pass away, that they have a life of their own, that they are not you but just thinking, and that you do not have to be ruled by them. Not feeding or reacting to impulses, you come to understand their nature as thoughts directly. This process actually burns up destructive impulses in the fires of concentration and equanimity and non-doing. At the same time, creative insights and creative impulses are no longer squeezed out so much by the more turbulent, destructive ones. They are nourished as they are perceived and held in awareness."
