Nichiren Daishonin states in “Questions and Answers between a Sage and a Foolish Man”:
The Buddha nature, which is inherent in all living beings, is called Myoho-Renge-Kyo. Thus if you chant this title of Myoho-Renge-Kyo once, the Buddha nature of all living beings will be called forth and gather around you.
The three enlightened properties of the Law, wisdom, and compassionate action of the true nature of the Law within you will be brought forth and then clearly manifested.
This is the state of enlightenment.
故唱一遍此首题，一切众生之佛性，皆被唤而集于此时，我身法性之法报应三身， 皆被牵引显现出来， 是谓成佛也。
