"...understand that you are not actually doing the witnessing. Of whatever happens, sitting in the morning, or the visions that come to you, merely look at them, but understand that you are not looking at them, there is no "you" as an entity witnessing them; witnessing takes place by itself.  So just be in your meditation and witnessing takes place of whatever there is to be witnessed. And don't even involve yourself in the witnessing. There is daylight outside.  Well, we see it; we don't have to make a statement: Ah, I am seeing the daylight there! So we are not witnessing; witnessing takes place automatically.
