With a relaxed mind, say a clock on the wall

With a relaxed mind, look at something, anything, say a clock on the wall. Mentally check to see if there is really a clock over there, seeming to exist on its own. Check to see if that clock has something to do with your mind, the conceptual mind that gives names, that designates. Train your mind to see reality more clearly. Repeat this exercise many times. Make this exercise part of your daily practice, make it a habit. After some time check to see if this exercise influences your view of emptiness and your meditation on emptiness.
