Buddha fulfilled the purpose of his advent in a little over 40 years, — the Great Teacher Zhiyi took about 30 years — and the Great Teacher Saichō, some 20 years. I have spoken repeatedly of the indescribable persecutions they suffered during those years. For myself, Nichiren, it took 27 years, and the great persecutions I faced during this period are well known to you all." According to the sect, the creation of the Dai Gohonzon image is the ultimate purpose of Nichiren's entrance into the Sahā world of humans. Furthermore, they claim that this particular Gohonzon was inscribed so that all people in the Third Age of Buddhism can attain Buddhahood in their present life existence (Sokushin Jobutsu). Nikko Shonin's last will and testament document to Nichimoku Shonin, "Articles to be Observed After the Passing of Nikko" ("Nikko ato jojo no koto"), states "...The Dai-Gohonzon of the second year of Kō`an (1279), which Nikko inherited, is hereby bequeathed to Nichimoku." Two original transfer documents exist written by Nikko Shonin. Of the two, the first document is a draft written in the second year of Gentoku (1330). The second is the actual transfer document itself, dated the first year of Shoukei (1332). Both documents are signed by Nikko Shonin. The signatures on these documents have been determined to be consistent with Nikko Shonin's signature from the period in his life. Additionally, the third High Priest, Nichimoku Shonin, stated "...The Dai-Gohonzon, which was entrusted upon the person of Nikko, is the plank Gohonzon. It is now here at this temple (Taisekiji)." From documents written by Nikko Shonin and Nichimoku Shonin, the Dai-Gohonzon was transferred between the successive high priests of Nichiren Shoshu. The sect further claims that the Dai Gohonzon may only be publicly enshrined for widespread access when Japan converts to this religion, including the Emperor of Japan who is charged the formal task to decree that a national shrine for the image can be built at the foot of Mount Fuji. The fourteenth High Priest, Nisshu Shonin, stated in his writing "On Articles to Be Observed after the Passing of Nikko" ("Nikko ato jojo no koto jisho"), "...The Gohonzon concerns the transfer matters of Taiseki-ji, which denotes the exclusive transfer from one high priest to another. The Dai Gohonzon of the High Sanctuary of the Essential Teaching, which Nikko Shonin inherited from the Daishonin and transferred to Nichimoku Shonin
