Who may perform the Eye Opening Ceremony?

"Nichiren states, "person" [not priest] who knows the heart of the Lotus Sutra is capable of performing the Eye Opening Ceremony. One who chants Namu Myoho renge kyo with the same faith as Nichiren Daishonin knows the heart of the Lotus Sutra and may perform the Eye Opening Ceremony." -- Shinkei Shonin Marcheso
