There are no individual and no collective victories in the Soka Gakkai. Nichiren teaches that those with incorrect faith invariably suffer loss while those with a correct faith gain victory after victory. Since SGI's faith and practice is lame, in the end, the believer will suffer loss. This is why, of the nearly 600,000 Gohonzons received in the society, fewer than 35,000 remain (6%).
On the other hand, practicing with the same faith as the Daishonin assures victory after victory, in one's personal life, family life and even in society. Practicing shakubuku towards unbelievers and shoju towards our fellow believers is certainly the dialogue for quick victory. Thusly, we can stop smoking, stop using drugs, radically change our diet and our health and bring joy to ourselves and others.
