The past is the observer. The past is the accumulated knowledge as the ‘me’ and the ‘we’, ‘they’ and ‘us’. The observer is put together by thought as the past. Thought is the past. Thought is never free. Thought is never new because it is the response of the past, as knowledge, as experience, as memory. And the observer is observing with the memories, experiences, knowledge, hurts, despairs, hope. With all that background he looks at the observed. So the observer then becomes separate from the observed.
