The Buddha does not stop simply at relieving suffering but teaches people the correct way of life and calls on them to transform their inner state of being and actually attain happiness. Shakubuku is none other than this compassionate practice of “removing suffering and imparting joy.”

Daisaku Ikeda

Aligning our hearts with our mentor and deepening our determination to advance kosen-rufu are key to achieving solid unity in the spirit of “many in body, one in mind.” It is through such unity that we can activate the true brilliant power of the Mystic Law.

Daisaku Ikeda

It is easy to be attracted to abstract ideals but difficult to challenge the realities of daily life. I hope that while upholding the magnificent ideal of kosen-rufu, you will spend your days in the actual practice of encouraging and motivating one person and then another and another to contribute to kosen-rufu. This is the practice, the hard work, of propagating the Mystic Law in the real world.
