a lower nature.

Some of the chief ones among those of the lower nature are anger,
hatred, jealousy, malice, rage. Their effect, especially when violent,
is to emit a poisonous substance into the system, or rather, to set up a
corroding influence which transforms the healthy and life-giving
secretions of the body into the poisonous and the destructive. When one,
for example, is dominated, even if for but a moment by a passion of
anger or rage, there is set up in the system what might be justly termed
a bodily thunder-storm, which has the effect of souring or corroding the
normal and healthy secretions of the body and making them so that
instead of life-giving they become poisonous. This, if indulged in to
any extent, sooner or later induces the form of disease that this
particular state of mind and emotion or passion gives birth to; and it
in turn becomes chronic.

We shall ultimately find, as we are beginning to so rapidly to-day, that
practically all disease has its origin in perverted mental states or
emotions; that anger, hatred, fear, worry, jealousy, lust, as well as
all milder forms of perverted mental states and emotions, has each its
own peculiar poisoning effects and induces each its own peculiar form of
disease, for all life is from within out.

Then some of the chief ones belonging to the other class--mental states
and emotions of the higher nature--are love, sympathy, benevolence,
kindliness, and good cheer. These are the natural and the normal; and
their effect, when habitually entertained, is to stimulate a vital,
healthy, bounding, purifying, and life-giving action, the exact opposite
of the others; and these very forces, set into a bounding activity, will
in time counteract and heal the disease-giving effects of their
opposites. Their effects upon the countenance and features in inducing
the highest beauty that can dwell there are also marked and
all-powerful. So much, then, in regard to the effects of one's thought
forces upon the self. A word more in regard to their effects upon
others.

Our prevailing thought forces determine the mental atmosphere we create
around us, and all who come within its influence are affected in one way
or another, according to the quality of that atmosphere; and, though
they may not always get the exact thoughts, they nevertheless get the
effects of the emotions dominating the originator of the thoughts, and
hence the creator of this particular mental atmosphere, and t
