What goes up must come down.  It is not just a law of nature, but of the
soul in human form.  It is the spirit’s
way of seeking balance, of bringing the human back to center.  If your emotions swing too far to one side
they will of necessity experience an equal and opposite reaction.  Why do we say “of necessity?”  For all in creation is essentially perfect—designed
to foster the perfect learning and growth experiences.  Through balance and the experience of being
off-balance you learn mastery.  Which
feels better and more natural:  being
centered and at peace or out of balance? 
You control just how high or low you go through mastery of thoughts.  No one said it would be easy, but the end
result is appreciation, gratitude, and the capacity to feel one’s true nature,
which is love.
