“Seth material” search engine (Jane Roberts)

At deep levels the cells are always working with probabilities, and comparing probable actions and developments in the light of genetic information. The most intricate behavior is involved and calculations instantly made, for instance, before you can take one step or lift your finger. This does not involve only the predictive behavior of the physical organism alone, however. At these deeper levels the cellular activity includes making predictive judgments about the environment outside of the body. The body obviously does not operate alone, but in relationship with everything about it. When you want to walk across the room, the body must not only operate using hindsight and “prediction” as far as its own behavior is concerned, but it must take into consideration the predictive activity of all of the other elements in that room.

You can literally choose between health and illness; between a concentration upon the mental more than the physical, or upon the physical more than the mental. Such private decisions affect the genetic heritage of the species. Your intent is all-important — for you can alter your own genetic messages³ within certain limits. You can cause a cell, or a group of cells, to change their self-image, for example; and again, you do this often — as you healed yourselves of diseases because of your intent to become well. The intent will be conscious, though the means may not be. Period. In such a case, however, the self-healing qualities of the cells are reinforced, and the self-healing abilities of the species are also strengthened.
