Thinking as a sense object is called “Vipassanuk “, but when we contemplate it become “Vipassana ” (insight). Wisdom will arise and we will be able to see by it. Seeing more, we will reach a peaceful spot, a staying point, a stopping point, a point of illumination. This is followed by cessation of suffering immediately if we know the movement of mind.
If we keep on observing our mind when we are thinking, the thinking will finally stop. Then voidness appears. If we persevere, we see nothing but emptiness. By following the mind constantly, the process will collapse.
