Practise just being aware, without attachment, judgement, action or identification. There's no need to stop thoughts. Be aware of thinking also. Although effort seems to be needed at first, really the mind is being drawn to your natural core effortless state of being aware.
Let go of seeking or avoiding, liking or disliking, partaking or abstaining, and be as you are. Let the world unfold as you witness it. You are, and you are aware. You perceive the thinking, the human form and the world. You are not the thinking, the human form or the world.
Practise just being aware throughout the day. When it occurs to do this, let go of holding on, let go of judging, let go of identifying with form, thought and action. Rest in the peaceful state of just being aware. It is your nature. Identifying with form (as a human) and thinking, leads to the sense and belief of the ego. It is the phantom ego that attaches to identity and ownership. It is the ego that judges what it likes and doesn't like, what is right and wrong. It is the ego that identifies as the doer of actions.
All the while you are the peaceful aware beingness. So let go of attachments and rest as the simple clear Awareness that you are, without form, without identity, without otherness.
You are naturally aware. No effort is needed to be aware. It is the nature of your being. You can perceive the efforts of the mind trying to just be. It cannot succeed in becoming just aware. You are the awareness within which the mind and it's efforts are perceived.
It is you, Awareness, in whom the mind dissolves when it seeks the true effortless nature of being.
