The canon of Nichiren reveals that Nichiren is Bodhisattva Jogyo, the leader of the Bodhisattvas of the Earth and the Supreme Votary of the Lotus Sutra:
"Then the Buddha declared, "There are my true disciples whom I have hidden at the bottom of the earth since gohyaku-jintengo. I will entrust it to them." So saying, the Buddha summoned those bodhisattvas led by Jogyo in the Yujutsu chapter and entrusted them with the five characters of Myoho-renge-kyo, the heart of the essential teaching of the sutra, [in the Jinriki chapter]."(ibid. Reply to Niiama)
Please note, "..led by Jogyo."
Why would anyone want to chant to a Gohonzon inscribed by Nissen rather than Jogyo? Why would anyone lecture extensively on Nissen rather than Nichiren?: "Priests of HBS deliver sermons (Gohomon) mostly quoting Nissen Shonin’s Gokyoka [poems] and expounding the correct meaning that these poems intend to give." (The Teachings of Honmon Butsuryushu by Nisso Fukuoka). Then why doesn't HBS follow the HBS teachings? Why do they appropriate the teachings of the orthodox sects and teach the faith and doctrines of Nichiren? I'll tell you why. Because both they and the HBS teachings are shallow, slanderous and heretical.
It is self-evident that Nichiren had the requisite faith and practice to inscribe the Supreme Object of Worship and to properly open its eyes. It is also self evident that there are as many deluded and misguided priests in Mappo as there are blades of grass on the pampas. We should have no faith in Nissen while we must have strong faith in Nichiren, the Supreme Votary of the Sutra. Chapter 21 of the Lotus Sutra states, "This man" referring to Nichiren Daishonin. Nichiren Daishonin states:
"That I, Nichiren have written out an Object of Worship, which will protect you, can not be inferior to the Lion's Roar."(Reply to Kyoo)
Nichiren also states, "This Gohonzon, "This mandala", or "I am entrusting you with the Gohonzon for the protection of your young child. This Gohonzon is the heart of the Lotus Sutra and the eye of all the scriptures. It is like the sun and moon in the heavens, a mighty ruler on earth, the heart in a human being, the wish-granting jewel among treasures and the pillar of a house.
When one embraces this mandala, all Buddhas and gods will gather around him,accompanying him like a shadow, and protect him day and night, as warriors guard their ruler, as parents love their children, as fish rely on water, as trees and plants crave rain, or as birds depend on trees. You should trust init with all your heart."(Upholding Faith in the Gohonzon).
Thus we see that "This man", in the Lotus Sutra, refers to Nichiren and "This Gohonzon" or "This Mandala", in Nichiren's Gosho, refers to the Gohonzon. Now if the Lotus Sutra had said, "These men" or Nichiren had stated: "Any Gohonzon", I might give the HBS and the other heretical sects the benefit of the doubt. However, in Mappo, the road is too tenuous and the path too narrow to rely on the Objects of Worship inscribed and eye opened by anyone but Nichiren. Even with Nichiren's Gohonzon there is a difference if one goes against the intent of the Sutra (not having faith that the Object of Worship is the Master of Teachings Lord Shakya of the Original Doctrine).
We read on many of the 130 or so extant Nichiren Gohonzon, the laudatory text, "This Object of Worship I have dedicated to the people of Jambudvipa."
