Through meditation
Meditating gives you practice in thought observation. How is this useful? It’s very useful. It can be the difference between acting rashly and acting calmly in the same situation. We all have times when that will come in handy, I know I do. That’s why the results of mediation are cumulative. That’s why they don’t usually come straight away. But they most certainly do come. As with everything, you just have to give it time. And all you have to do is practice observing your thoughts.
