Here is a simple but very useful lesson from Eckhart Tolle about thinking, breathing and awareness.
Thinking is no more than a tiny aspect of the totality of consciousness, the totality of who you are.
Time is seen as the endless succession of moments, some “good”, some “bad”….
Yet, if you look more closely, that is to say, through your own immediate experience, you find that there are not many moments at all.
Most egos have conflicting wants. They want different things at different times or may not even know what they want…
…except that they don’t want what is: the present moment.
Be aware of your breathing. Notice how this takes attention away from your thinking and creates space.
