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.
