" Whatever we can observe, like a cup upon the table, is an object and exists apart from our awareness, which is its perceiver. Yet we cannot only observe external objects, we can also observe internal objects. We can note whether our sense organs are acute or impaired, as when our vision begins to fail. Similarly we can observe our emotions, our thoughts, and even our own ego, which are all fluctuating phenomena, if we look deeply. We can observe the functions
of the mind just as we can observe the movements of our body.
Just as the eye is not damaged when a cup falls onto the floor and breaks, so consciousness is not damaged when the contents of the mind get altered or damaged. The witnessing consciousness is apart from the objects and conditions that it observes. Therefore, the first thing we observe about the mind is that, as something observable, the mind is an object. The mind is material and part of the external world. It belongs to us but it is not who we really are, just as our house belongs to us but is not us. This may be shocking to consider, but it is really something intuitively known to us. When we speak of "my mind," we are defining the mind as an object that belongs to us and not as ourselves. "
