Just looking at a roseflower, watch it; or at the stars, or the people passing on the road, sit by the side and watch. And then slowly slowly close your eyes and see the inner traffic moving -- thousands of thoughts, desires, dreams, passing by. It is always rush hour there.
Just watch as somebody watches a river flowing by, sitting on the bank.
Just watch -- and watching, you will become aware that you are not it.
Mind is being identified with it. No-mind is being disidentified with it. Don't be a mind, because in fact you are not a mind. Then who are you? You are consciousness. You are that watchfulness, you are witnessing, you are that pure observation, that mirrorlike quality that reflects everything but never becomes identified with anything.
