2. Blood and Nerves

For example, when you see a tree trunk lying on the ground, you see an external reality. But if you think about this tree trunk, you will find it is not a reality at all because it cannot exist as such. It necessarily has to contain the shoots that develop into branches, leaves, and blossoms. Thus, it is really a lie, this tree trunk, a “true unreality,” because what it appears to be cannot exist in the nature of things. Only if you are aware that you think of something unreal when you think about a tree trunk, then your thinking is true to reality.
