Balance and alignment. 
You do this on a regular basis to your car, do you not? 
If you fail to do this, the car wobbles and does not ride
efficiently.  How do you balance the
self?  Listen to your thoughts.  Are you in alignment with your highest
nature?  How do you know?  You go to the center of the soul—the heart.  This is the seat of the soul—the driver’s
seat.  When you let the head drive your
actions, you wobble just like the car. 
Seek balance and alignment in all things, beginning with your thoughts.
