Answer: The death of the corporeal body does not unite or separate people. Our body is like a small animal that lives next to its master.
Question: Can the fear of death push us to unite?
Answer: The fear of death does not motivate us to do anything. Every living creature is afraid of dying. The fact that the body ceases to function is a natural state and nothing more than that. You should not associate the soul with the body in any way. It is a very big mistake.
