as they lose the senses, they go through intense emotional experiences of grief, rage, etc.
At the end of the movie all that is left is the feelings & thoughts of two lovers.. the world apparently disappearing from them.
With all sensory experience gone, would there be anything left?
"Questioner: You keep on saying that I was never born and will never die. If so, how is it that I see the world as one which has been born and will surely die?
Maharaj: You believe so because you have never questioned your belief that you are the body which, obviously, is born and dies. While alive, it attracts attention and fascinates so completely that rarely does one perceive one's real nature. It is like seeing the surface of the ocean and completely forgetting the immensity beneath. The world is but the surface of the mind and the mind is infinite. What we call thoughts are just ripples in the mind. When the mind is quiet it reflects reality. When it is motionless through and through, it dissolves and only reality remains. This reality is so concrete, so actual, so much more tangible than mind and matter, that compared to it even diamond is soft like butter. This overwhelming actuality makes the world dreamlike, misty, irrelevant."
