Around 1890 a Blackfoot Indian chief was dying.  His name was Isapwo Muksika Crowfoot, and he whispered these words into the ear of a missionary father:

What is life?
It is the flash of a firefly in the night,
It is the breath of a buffalo in the winter time,
It is the little shadow that runs across the grass
And loses itself in the sunset. 

The part of us that we know already is the part that flickers out all too fast.  Far better to seize this time and become timeless.  When you feel a new impulse, an uplifting thought, an insight that you have never acted upon before, embrace the unknown.  Cherish it as tenderly as a newborn baby.  The unknown is the only thing that truly cares about the fate of your soul; therefore it would be good to revere it as much as you revere holiness.  God lives in the unknown, and when you can embrace it fully, you will be home free.
