The food benefits the soul only if it is utilized by the cells. But the nourishment that the soul craves does not satisfy the cells. Hunger and satisfaction are not even simultaneous in both, at least not as regards the same food. As a rule, the soul comprehends hunger when the cells are satisfied and _vice versa_. The soul’s hunger ceases the moment suitable food in sufficient quantity is introduced in the stomach. But this does not help the cells. Because, if the food remained in the stomach, to the satisfaction of the soul, the cells would soon die of starvation. The nourishment in the stomach is of the same importance to the cells as the provisions stored in the warehouse of the community are to the human individuals. These also would die from hunger if they let the victuals remain in the stores. The people must undertake to distribute, prepare and consume the food. Similarly the cells would starve to death unless they prepared the food in their common storage to suit their wants. The nourishment must be transformed into blood through the whole complicated process we call digestion. When this is done, the cells are able to satisfy their craving, and simultaneously a new hunger-feeling arises in the soul. Although it is the _same food_ that satisfies both parties, it is the same food administered in different forms, at a different time, and in a different mode. We are concerned with dissimilar beings possessed of wants at once different and yet most intimately associated. The connection is not difficult to understand. When the soul comprehends the need of the stomach, it is the collective want of the cells that comes to expression as the individual want of the soul. The different needs receive in different form an identical substance and this fact is obviously the connecting link between the soul and the cells. We might without difficulty carry out the same reasoning in regard to respiration and all the other physiological processes of the body.
