You cannot lift a boulder that is too heavy for
you.  And so, you have several choices.
You can leave it there blocking your path and make no progress.  You can break it into smaller pieces and
carry off one or two stones at a time. 
You can ask for help and move it with those who are best suited to help
you.

At times in your spiritual journey you find that
you are making no forward progress.  If
you are brave enough to look into the darkness and shine a light, there you may
find not just small stones in your path that need clearing, but a major
boulder.  We have now exposed some
options for you to take.  If you are
brave enough to expose the boulder, then you may be ready for the next
step.  Prepare to widen your path.  Beautiful things lie ahead, we assure you,
but at times you must do the heavy lifting.
