I've been listening to Eckhardt Tolle on Apple Music almost every morning since May 20, 2025. He talks a lot about not thinking and rising above thought.
Most thinking is useless and harmful. When you are thinking, it's either about the past or the future, and you are not in the present moment. There are times for thinking about the past and the future but it's not all the time.
Once I started trying not to think I noticed how much and how often I am thinking. It is constant.
When I catch myself thinking I try to stop by concentrating on my breathing and sense perceptions (touch, sight, sound, etc.). I still struggle with it most of the time.
It takes practice. I am hoping one day it will be something that comes easy to me.
