Life-Giving Factors
If there were no air, and if sunlight and other factors of the environment and atmosphere did not interact with the body, there would be no physical body. Such forces nourish the body and maintain it, for a body and bloodstream have no function or meaning by themselves without interaction from these factors. It should be known that most of these factors that cannot be seen are spiritual. The seed of a tree without sunlight, air, spiritual effects, astral, and atmospheric factors will not develop. It will not flourish. Only when all those external factors are in effect, can it become a tree. These factors are different from the seed itself, the embryo, internal shell and skin, and other visible parts. A tree can grow solely after the elements react to its seed effectively.
