Overdoing it.  You have a habit
of this at times, do you not?  And what
happens when you become a bit too active, a bit too emotional, a bit too
anything?  Why, you experience the
opposite of whatever you experienced as the pendulum swings back the other way.  The soul is always seeking balance, and
overdoing takes you away from the center. 
Are you feeling frazzled, hyperactive, or any of the many ways the body
and spirit work together to try and give you notice that you have strayed quite
a bit from the center?  Pay attention.  How do you return?  Ease back into it, for this is what the
center represents:  peace and ease.  Easy does it, my friend.  Easy does it.
