As it is explained in many of the meditation teachings, first of all you cannot stop thoughts. It is impossible. And stopping the thought is not our agenda. It is not doable. Even it is doable it is not necessary, it is useless. Meditation actually is to generate the awareness of the thought. If you are supposed to develop the awareness of the thought, then you have to have the thought to be aware of. So you can’t really get rid of the thought and then try to look at something.
