I just love this question on mindful meditation and how to address those annoying thoughts that keep popping in. This was something I found quite challenging when I started practicing insight meditation. It’s not that I’ve mastered meditating now; it’s simply that I now know how to observe the stream of thoughts and not engage or relate to them. Sometimes we need that little reminder- we are not our thoughts. Observe them and let them go.
I have read a lot about mindfulness practices a month ago, and I have been practicing observing my thoughts and emotions since then. But this feels very stressful to me because I can observe negative and unproductive thoughts coming in my mind, but I cannot stop them. They come spontaneously and create emotions in my body even when I don’t want them to come. And most of the times, the thoughts come and compel me to act, and when I regain my attention in the present, I have already acted upon those thoughts. How do I change this? So, that I get much more control over my mind and form positive thinking habits.
Mindfulness is not about stopping thoughts, it is the disinterested stance of awareness that observes thoughts as they come and go. That perspective shows you that you are not your thoughts, but rather your mind entertains thoughts. That develops self-awareness and that will undo the compulsion and reflexive action you feel in your thoughts currently. The instinct to act upon a thought is based on the unconscious beliefs held about that thought. Mindfulness will illuminate those unconscious beliefs and neutralize their compulsive, addictive hold on you.
