"Heaven and Earth give themselves. Air, water, plants, animals, and humans give themselves to each other. It is in this giving-themselves-to-each-other that we actually live. Whether you appreciate it or not, it is true." - Kodo Sawaki (沢木 興道, 1880-1965), one of the most prominent Japanese Soto Zen teachers of the 20th century.
Man sacrifices his health to make money. Then sacrifices money to recuperate his health. He is so anxious about the future he doesn't enjoy the present. He lives as if he is never going to die, and then dies having never really never lived.
