How does it work?
While most of what we achieve is by “doing”, mindfulness achieves its ends by “not doing,” simply by observing. It seems to achieve its success by allowing us to see our thoughts and emotions for what they are, thoughts we are having at the moment and emotions we are experiencing.
Thoughts like “I must be stupid” are subtle and we generally believe them uncritically. By being mindful of our thoughts we gradually get the idea that the are just thoughts that we are having and there is no need to believe them uncritically. Similarly with a feeling like “anger” we start to realize that it is a feeling that is currently strong within us but no more than that, we currently have anger, but it doesn’t define us and it will pass. We stop identifying with the thoughts and emotions. Our mind ceases to be in the control of strong feelings and thoughts and slowly comes under our own control.
