"Dragons have the job of making the rain fall -- this same work can be regarded as a burden or as a mission, depending on how one looks at it. This difference in outlook or attitude is also what determines whether we will be defeated by negative influences, or evil friends, or successfully attain Buddhahood. Truly, as the Daishonin says, 'It is the heart that is important' (WND-1, 1000). And this difference in heart or spirit comes down to whether or not we embrace the 'great vow' that is mentioned in this letter.
"To bring our practise of the Lotus Sutra, or the Mystic Law, to successful completion means that we must eagerly and joyfully embrace the mission of taking on the sufferings of still more and more people and of challenging even greater difficulties in our cause for human peace and happiness. The Daishonin urges us to actively seek this way of life, to valiantly climb the Dragon Gate of faith as successors of kosen-rufu, and attain Buddhahood without fail. As practitioners of the Mystic Law, this is what it means for us to 'live based on a great vow.'"
