There are two types of benefits in chanting Namu Myoho renge kyo, inconspicuous and conspicuous. Referring to inconspicuous benefits, Nichiren teaches:
"Why do you not, if only this once, try planting the wonderful seeds that lead to eternal and unchanging Buddhahood? Though at present you may taste only a tiny fraction of the everlasting joys that await you in the future, surely you should not spend your time thoughtlessly coveting worldly fame and profit, which are as fleeting as a bolt of lightning or the morning dew."
"Since childhood, I, Nichiren, have never prayed for the secular things of this life but have single-mindedly sought to become a Buddha."
Since neither Toda nor Ikeda were enlightened, why follow them or their unenlightened organization rather than Shakyamuni Buddha, Nichiren Daishonin, and their organization?
As far as conspicuous benefits, there are testimonials in every religion but here again, we look to Nichiren. Nichiren's ability to survive far surpassed other religious and secular figures such as Jesus, Osama Bin Laden, and Napoleon. He attributed his survival to Namu myoho renge kyo.
