A man attached to the body accumulates money with great struggle to expand and protect the position of his wife, children, property, domestic animals, servants, homes, relatives, friends, and so on. He does all this for the gratification of his own body. As a tree before dying produces the seed of a future tree, the dying body manifests the seed of one’s next material body in the form of one’s accumulated karma. Thus assuring the continuation of material existence, the material body sinks down and dies.
