In his "Commentary on the Kegi Sho", the fifty-ninth High
Priest of Taisekiji, Nichiko Hori, makes the following
statement:

"In the final analysis, faith, heritage and the water of the Law are one and the same.  Through faith, the believer receives the water of the Law from the Original Buddha.  The water of the Law thus received flows within the believer's life, just as blood circulates within the human body.  For this reason, to convey the water of the Law through faith is to transmit the heritage.  Therefore, faith should never be disturbed or shaken.  If it is disturbed, the water of the Law will cease to flow. Or, even, if it continues to run, it
will become defiled and irregular, thus cutting off the flow of Buddhism itself.  As long as faith remains unshaken, the pure and immaculate heritage of Buddhism will continue to flow with vigor, not matter how many ages may pass."

Question: Who is the Original Buddha HP Hori speaks of?

Nichiren says in "Reply to sairen-bo"

"When Shakyamuni Buddha, our original teacher appeared inthe world in order to expound the Lotus Sutra, like shadows and echoes the Buddhas and bodhisattvas of the other worlds came forth and assisted him in his efforts to spread the
teachings."

Nichiren then says in "The Buddha's Own Mind"

"Rejecting Shakyamuni Buddha, who is the sovereign, teacher and parent of our present world, they pray to escape to another world......and that belongs to a complete stranger. Why do Believers in the Nichiren Shoshu and Gakkai Philosophy disregard Shakyamuni? Why do they ignore the
words of Nichiren himself?  Their own High Priest (Hori) says that the flow of Buddhahood is cut off if the Original Buddha is not the source of the flow.  But how did they ignore Nichiren's own words and change the identity of this Original Buddha?   Who would believe anyone but Nichiren?
It's folly to take the word of later High Priests of
Taisekiji when they contradict the words of Nichiren.

Nichiren says in, "The Buddha's Own Mind": "The people of today, however, believe the pronouncements of their own teachers to be the golden words of the Buddha.  Thus they place such pronouncements on the same level as the Lotus Sutra, considering the two to be equal authority; or they regard these teachings as superior to the Lotus Sutra; or they reason that, though their teacher's pronouncements are
inferior, they are well suited to the capacity of the
people."

How many times have we read that Sokagakkai has modernized Buddhism? Daisaku Ikeda has made Buddhism easily understood for the modern age? The "Human Revolution" is the modern day Gosho? Nichikan is the great restorer of Buddhism? Or as I
posted in another post: From the LIPS of DAISAKU IKEDA "....He knew all too well that the age of the Latter Day of the Law had already come, when prophecy foretold a decline in the power of Shakyamuni's Buddhism; he knew it would have
been entirely inappropriate to bring back Shakyamuni's Buddhism as a new set of beliefs.  He was able to bring the people a totally new kind of Buddhism because he was convinced of his identity and missions to save all people of the Latter Day of the Law." Daisaku Ikeda (pg. 212 Selected
Lectures on the Gosho)

The lineage of the High Priests at Taisekiji has obviously been broken many, many times. HP Hori points out that one should take their lineage from the Original Buddha, Shakyamuni. The big question is, why do the members of Nichiren Shoshu still accept the "unbroken lineage theory", when we have proven the lineage has been "broken many
times." Why do Nichiren Shoshu'ers turn their back on Nichiren and our Original Teacher, Shakyamuni in favor of Daisaku Ikeda, or Nikken? There is no proof that the DaiG is real, yet Shoshuers believe? No proof that Nikko is the true successor, yet Shoshuers believe? Nichiko Shonin, from Taisekiji states:

"If we ignore Nichiren and Nikko, and disobey the Buddha's will by following heretical or blind belief, the river of the Law will become blocked, and they will be pushed back in mind and body, to the state of benightedness. They will lose their right to the lifeblood which enables one to attain Buddhahood in the flesh!"

From Nichiren in the "Kanjin Honzon-Sho"
"Shakyamuni within our minds, is an ancient Buddha without beginning, manifesting Himself in the three bodies, and attained Buddhaood in the eternal past described as 500 dust-particle kalpa ago."

From the Lotus Sutra, 16th chapter.
"I (Shakyamuni) am always here and I shall never pass away."

 The Lotus Sutra of the Original Buddha, Shakyamuni ,
point to many humans that have attained enlightenment by practicing with Shakyamuni as the Eternal "True" Buddha.
