As the entirety of the sun is reflected in every glistening droplet of water, so is the entirety of life reflected in your individual lifetime.
And in each of your years, you pass through the entirety of your life.
And in every day of your life you are born, live your life through, and pass on from this world.
All your life lies in the hands of today.
