One reason Soka Gakkai members fail to attain enlightenment

"The only way to enlightenment is to believe in the Buddha." -- Nichiren

"We can not observe the precepts, We can not practice meditation. We can not obtain the wisdom of the Buddha. The only way to enlightenment is to believe in the Buddha. Our belief in Shakyamuni Buddha is expressed by the chanting of the Sacred Title Namu Myoho renge kyo." (Shishin-gohon-sho) -- Nichiren
