The value of every second

Though death is inevitable for every being born, everyone cherishes their own life, and naturally seeks to extend it.  Though death is inevitable, would you not extend your life a decade?  A year?  A day?  A minute?  So it is a mark of progress in training to recognize that every second of a day matters, every second is full of the opportunities of life.  It is easy, understanding this, to live every moment with love and joy in such an opportunity as life presents, and come to understand the true value of your life.  Yet it is much more difficult, understanding this value of your own life, to see the value of every living being.  And then to perfect your interactions with every being, so that at every second of your shared living, to act in love for the precious nature of that life you share.  Such mastery of understanding requires much training.
