I was wrong to assume Mind has a physical existence. It's an invalid to assert properties of minds and rocks together. Rocks are material, and Mind is not. Mind does not have any physical property. It is a property we sometimes ascribe to some matter. A human brain at birth contains matter, at death contains different matter. Both times contain the same mind. Human brain contains the same matter before death and right after death, brain before has mind property and does not have the mind property after.

What is the logic to say rocks do not have a mind? Just because we can not perceive the mind does not prove it does not exist. A tree falling in the forest always makes noise (air vibrations) with out a mind to hear the sound.
