Background and Summary(Short Story)
Nichiren Daishonin warned his follower Shijō Kingo about upcoming difficulties due to practicing the Lotus Sutra. In a letter, Daishonin explains that true happiness lies in chanting Nam-myoho-renge-kyo, and one should accept suffering and joy as part of life while continuing to chant. This leads to experiencing the boundless joy of the Law, or Buddhahood.
