Chanting about challenges in our life and chanting for kosen-rufu, the aspiration to help all people become happy, are essentially one and indivisible. Both propel us forward.

When we chant strongly for the development of the Soka Gakkai, which is advancing kosen-rufu, we forge invincible inner strength and attain the towering life state of champions.
