The way to happiness is not complicated. Those who chant Nam-myoho-renge-kyo consistently in the realm of kosen-rufu triumph in the end. They are certain to attain a state of absolute happiness—in other words, the life state of Buddhahood. If you remember this single important point, your life will always be solid and secure.
