Gohonzon

"The Gohonzon exists only within the mortal flesh of us ordinary people who embrace the Lotus Sutra"

and "This Gohonzon also is found only in the two characters for faith."

Nichiren also says, 

"I am entrusting you with a Gohonzon for the protection of your young child. This Gohonzon is the essence of the Lotus Sutra and the eye of all the scriptures. It is like the sun and the moon in the heavens, a great ruler on earth, the heart in a human being, the wish-granting jewel among treasures, and the pillar of a house.

When we have this mandala with us, it is a rule that all the Buddhas and gods will gather round and watch over us, protecting us like a shadow day and night, just as warriors guard their ruler, as parents love their children, as fish rely on water, as trees and grasses crave rain, and as birds depend on trees. You must trust in it with all your heart."

and

"Bodhisattvas such as Manjushrī, who lives in the Golden-colored World, Maitreya, in the palace of the Tushita heaven, and Perceiver of the World’s Sounds, on Mount Potalaka, and Bodhisattva Medicine King, who is a disciple of the Buddha Sun Moon Pure Bright Virtue, all vied with one another in asking [the Buddha’s permission to propagate the Gohonzon in the Latter Day of the Law], but he refused. The Buddha declared: “Those bodhisattvas are known for their excellent wisdom and profound learning, but since they have only recently begun to hear the Lotus Sutra, their understanding is still limited. Thus they would not be able to endure the great difficulties of the latter age. My true disciples I have kept hidden in the depths of the earth for numberless major world system dust particle kalpas. I will entrust it to them.” So saying, the Buddha summoned Bodhisattva Superior Practices and the other bodhisattvas in the “Emerging from the Earth” chapter and entrusted them with the five characters of Myoho-renge-kyo, the heart of the essential teaching of the Lotus Sutra."

and

"I HAVE offered prayers to the Gohonzon of Myoho-renge-kyo. Though this mandala has but five or seven characters, it is the teacher of all Buddhas throughout the three existences and the seal that guarantees the enlightenment of all women. It will be a lamp in the darkness of the road to the next world and a fine horse to carry you over the mountains of death. It is like the sun and moon in the heavens or Mount Sumeru on earth. It is a ship to ferry people over the sea of the sufferings of birth and death. It is the teacher who leads all people toBuddhahood and enlightenment. This great mandala has never yet been propagated anywhere in Jambudvīpa in the more than 2,220 years since the Buddha’s passing."
