Belief in a mentor, priest, guru, supreme being, oneself, or Myo Ho Ren Ge Kyo?

"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]
