What are the Three Great Secret Laws?
The Three Great Secret Laws are the principles that constitute the core and foundation of Nichiren Shoshu Buddhism. They are the True Object of Worship of the Essential Teaching, the High Sanctuary of the Essential Teaching, and the Daimoku of the Essential Teaching.
The True Object of Worship is the Dai-Gohonzon, inscribed by Nichiren Daishonin on October 12,1279. Within the Dai-Gohonzon are the person and the Law. The person is the eternal enlightened life of the True Buddha, Nichiren Daishonin. The Law is Nam-Myoho-Renge-Kyo to which the Daishonin is eternally enlightened.
The True High Sanctuary is the place where the Dai-Gohonzon will be enshrined at the time of kosenrufu so that all the people in the world can eradicate their negative karma and attain enlightenment. At the present time it is enshrined in the Hoando Enshrinement Hall at the Nichiren Shoshu Head Temple, Taisekiji. In a general sense, it also signifies the place where the Gohonzon is enshrined in local temples and believers’ homes.
The Daimoku of the Essential Teaching is Nam-Myoho-Renge-Kyo. It carries the significance of both faith and practice. Nichiren Daishonin established the Daimoku of the Essential Teaching by chanting Nam-Myoho-Renge-Kyo for the first time on April 28, 1253
