The Nyaya-Vaisheshika theory is a theory of the Mind-Body Problem proposed by ancient Greek philosophers, not Indian philosophers.

According to the Advaita Vedanta theory, the mind and the body are two aspects of the same reality, which is Brahman. Brahman is the ultimate reality, which is pure consciousness and bliss.

According to the Dvaita Vedanta theory, the mind and the body are two distinct entities. The mind is a conscious entity, while the body is a material entity.

According to the Vishishtadvaita Vedanta theory, the mind and the body are two aspects of the same reality, which is Brahman. Brahman is the ultimate reality, which is pure consciousness and bliss.

The Mind-Body Problem is a problem because we do not know how the mind and the body interact, we do not know what the nature of the mind is, and we do not know what the nature of the body is.

The argument from the nature of death is not an argument for the Advaita Vedanta theory of the Mind-Body Problem. It is an argument for the Dvaita Vedanta theory.

The argument from the nature of death is not an argument against the Dvaita Vedanta theory of the Mind-Body Problem. It is an argument for the Advaita Vedanta theory.

The argument from the nature of hallucinations is not an argument against the Vishishtadvaita Vedanta theory of the Mind-Body Problem. It is an argument against the Dvaita Vedanta theory.

The Mind-Body Problem has implications for our understanding of the nature of reality, the nature of consciousness, and the nature of free will.

All of the above are possible solutions to the Mind-Body Problem.
