2. Blood and Nerves
Our nerve substance has been transferred into the earthly realm; it exists here on the earth where we live as physical beings. Thus, we all bear something of extraterrestrial origin in us that has been transplanted onto the earth. This is a very important fact, for the nerve substance, as it rests in us, is actually dead. You need only open any current anatomy or physiology textbook to see that in terms of substance, nerve substance is the most durable in our body. It is the one most resistant to change and, like the blood substance, least subject to direct, mechanical interference from the outside. Our nerve substance is affected by influences of our sense perceptions, but it cannot be influenced directly and mechanically because it was originally a living substance and is now dead because we as earth beings carry it in us. We might say if it were not paradoxical—though it is true in a spiritual sense regardless of any paradox—that if we could take our nerve substance and raise it to a sphere beyond the influence of earth forces, it would become a marvelous, living, vibrant being.
