Yoshiro Tamura: Joy

Chapter 18 explains in detail the joy that is the first of the five kinds of faith in the previous chapter. Suppose someone rejoices upon hearing the sutra and passes it on to others, enabling them to pass it on with joy to still another person, until it has reached the fiftieth person. That joyous person’s blessings will be far greater than those of someone who has donated many treasures or achieved the highest mental state of Small Vehicle Buddhism, that of the arhat. How much greater, it says, are the blessings of the initial person who hears the sutra and rejoices. That person’s blessings are beyond comprehension. This has been called the joy of a fifty-person line of transmission.
