The Grand Design

I cannot see what is left in front of me; I cannot look beyond the grain of sand that sits gently in my hand. What is time? How much is left? That little grain of sand is all I have, all that I know - a tiny insignificant piece of a larger puzzle. It has a place among all the other grains of sand in the universe - related to each, but different in the infinite world, like that of a fingerprint. How can I let it go? I have held it for some time, it has become my companion, it comforts me in times of need, never abandoning me, quietly listening. I will try to nurture it, try to save it for others who come. I will try to treasure the time, and try to leave a lasting impression with it. How much time is left?
