Genuine growth comes from stretching.  A balloon expands to a certain size when you
blow it up, and then you stop.  There is
fear of stretching too far.  Yes, there
comes a point where it will burst, but are you satisfied with having your
balloon the same as all others?  Would
you like to try to expand the spirit just a bit more?  You are not like a balloon in the physical
world.  You as spirit can stretch and
grow with no bounds without bursting. 
Step outside of the physical box you have put yourself in and expand
your consciousness.  You do this by
trying new ideas and beliefs.  Never
stagnate.  Life is about the experiences
you have and how you grow from them. 
Prepare for lift-off.
