Nichiren refutes the bizarre SGI/Tibetian/Zen teaching of Mentor [Guru or Master] and Disciple

"If I add my own interpretation it will be as if I had profaned these passages, but in essence they mean that Shakyamuni’s practices and the virtues he consequently attained are all contained within the five characters of Myoho-renge-kyo. If we believe in these five characters, we will naturally be granted the same benefits as he." [True Object of Worship]
