While we can practice being mindful in everyday life by just observing what is happening around and within us, formal training by way of sitting meditation is most effective for developing mindfulness skills. This is because the formal meditation context prevents the inevitable entanglements with daily stimulations and allows us to focus specifically inside ourselves. Meditation enables us to reprocess our internal experiences, including painful memories, with more awareness, neutrality and acceptance. During mindfulness meditation, we sit closed eyes and initially focus on the breath to develop concentration and take control of our attention. This alone helps decrease the intrusion of unhelpful thoughts that we may have. During this training, all sorts of thoughts frequently arise. Instead of being caught up in a thought, we learn to see it for what it is, just a thought, an impermanent mental event, no matter what the content of the thought may be, and go back to our focus of attention. In this way, we learn not to react to thoughts. We gain a direct experience that thoughts cannot truly affect us or define who we are. Similarly, when we pay attention to our body sensations, we also learn to perceive a body sensation merely as a body sensation, regardless of how pleasant or unpleasant it is. Mindfulness training helps us realise that body sensations, like thoughts and all other experiences, are also impermanent by nature and no matter how pleasant or unpleasant they are, they pass away. As we become more mindful of this reality, it becomes increasingly easy to observe that body sensations are essentially an experience that cannot affect us unless we react to them. Body sensations are significant because they are the only means by which we can feel emotions. Accordingly, training ourselves to not react to them helps us accept and let go of emotions, rather than suffer from them. This is called emotional regulation.
