"There is spiritual matter in everything, but it cannot be seen or sensed physically unless it is revealed to one by a force on the spiritual side. Or rather, it cannot be understood unless revealed, for it can always be seen through its effects. By this I mean that it leaves a trace in the physical realm, like a jellyfish that leaves a glowing trail in its wake. When the brain of a human thinks, it is not the actual brain that is thinking, instead it is the spiritual matter that exists in the brain, and this spiritual matter leaves a trail where it goes of electric signals and such. When someone feels a certain emotion, such as love or depression, it is felt in the spiritual realm, but its traces are seen in the physical, such as certain chemicals, but these are not the cause of the emotion, only the effect of them. It is possible, through certain drugs, to induce varying emotions, such as happiness or laughter, but these are not the actual emotions, only their physical counterparts, so that while it appears to be happiness, it is not, like the shadow of a man in a field: his form keeps the light from striking the ground beside him, but the shadow is not him, only the trace of him. Making a shadow like the man does not make the man, only the appearance of the man. While the how of a situation may be inferred through physical means, the why is an entirely spiritual matter, and any attempt to observe life without taking into account the spiritual matter behind it will end in the same result as evolution, as the scientists of your day generally imagined it, but which was, in fact, devolution. "The laws of the physical realm are called science, such as the fact that energy and matter are neither created or destroyed in any natural or artificial process, or that everything left to itself tends toward disorder, or that life cannot come from non-life by natural or artificial processes. The laws of the spiritual realm are called morality. You have no doubt observed that when one does a certain thing, the end result is always good, and when one does something else, the end result is always bad. That is because there are spiritual laws that govern life, and just as there is gravity on the earth that always pulls things down to it, so there is a spiritual law that whenever someone steals something, the result is suffering for both of the parties involved. Just as it is a physical law that man must have oxygen to live, so it is a spiritual law that when someone murders another the end result is always suffering. Why is this, one may ask, but that is a foolish question, or at least a pointless one, for the law of gravity states that on the earth, all things fall downward towards the center of gravity, there is no reason why, except that it is, for it is observed continually to be the case.
