"The Daishonin says:
"'Make no mistake. If you abandon your faith in the Lotus Sutra now, you will only make yourself the laughing-stock of your foes. Shamelessly pretending friendship, they will try to maneuver you into recanting, with the intention of later laughing at you and letting others ridicule you as well. Let them say all they have to say. Then tell them, “Instead of advising me in the presence of many people, why don’t you admonish yourselves first?” With this remark, abruptly rise from your seat and depart.' (WND-1, 801)
"The Daishonin consistently urges Tokimitsu to speak out bravely for his beliefs, to be mentally prepared, and not to be afraid. Telling him to the effect: 'Clearly and boldly refute falsehoods! Now is the crucial time! Fulfill your vow!'
"In this way, the Daishonin outlines the spirit that all of his youthful followers should embody. It is none other than the fighting spirit of our ever-youthful SGI. The essence of dialogue is courage and dynamism. The only way to vanquish devilish functions is with a mighty lion’s roar. He indicates, therefore, that youth need to face up to powerful opponents and challenge difficulties. A powerful opponent makes us strong, and difficulties represent opportunities for doing our human revolution."
