Emptiness doesn't depend on differentiation, or distinguishing correctly between objects

. You must be talking about some conceptualization of it, that I am not familiar with. Emptiness in not removal of anything.
to say that karma and mind are like the bay its river is a very coarse false superimposition, since its saying that karma is unreal: nonexistent except for being a conceptual mental image within a conceptual consciousness
If you want to discuss materialistic approach to reality, it will be hard for you to see my point. What more then a presence before the mind is a beer can, or imagined bay? Materialistic knowledge about it. Those two are no different. People that dream, should know that perfectly. In your dreams you hold the materialistic view and attach it to imagined objects. Beside this experience... the brain doesn't even have mechanisms to bring outside world directly to awareness. Light is changed into electric impulse in your eyeball, so even the beer can you see is nonexistent, conceptual mental image, as it has to be projected out of binary data.
Is it enough for you?
Phenomena should be examined from the experiencer point of view, not from materialistic knowledge.
