If life, in the form of a non-material entity, can exist independently then there would not be a need for a physical being in the first place. The simpler solution is usually the most economical. So life must require a physical form to exist in the first place. The mind or soul is therefore a product of the body, not the other way around. Nor is the mind/soul independent of the body.
Yet, the body is what produces the very illusion of the soul in the first place. It is a part of the material world and it is a necessary part of our humanness. Without this we would not know what we know, and we would not live how we live. That is the irony of the mind and body.
