Shobo defined Mt. Omine as the sacred mountain of Ichijo-shinjitsu (the mountain of absolute doctrine that only one teaching, the Lotus Sutra, can lead to enlightenment), not a mountain of Nijo/sanjo hoben (the mountain of tentative teachings aiming to entice people into real teachings).
聖宝は、大峯山を二乗・三乗の方便の山でなく一乗真実の山であると定めた。
