Your body is on loan to you.  It is a gift. 
When you own a thing, do you not have a tendency to take it for granted
and to not treat it as carefully as if you know it belongs to Another?  Treat it with kid gloves.  What does this mean?  Handle it with care, lest you have to return
it and explain why you were so careless. 

Now, knowing that this vessel which houses your
spirit is not really yours, why do you also take credit for its ailments?  “My cold, my cancer, my heart attack,” and
the like.  If the vessel you have
borrowed is not quite perfect, is that a result of how you have treated it or
was it slightly imperfect to begin with? 
No matter!  The one who is
temporarily using that vessel is perfect, beautiful, and eternal.  You have borrowed and agreed to use your
vessel for a very good and valuable purpose:  to let your light shine.  How are you doing at that?
