The Nichikan and Nichiren Shoshu "Gohonzons" do not embody the Buddha's world because they lack Lord Shakyamuni as eternal Buddha. When one worships a Nichikan Gohonzon, the Buddha fails to hear your prayers. This is similar to a radio which must be set to a particular frequency in order to listen to your favorite radio station. Nichiren's authentic Gohonzon (Honmon no Honzon). embodies the Buddha's world as described in the Sixteenth Chapter of the Lotus Sutra. The difference is apparent when you enshrine a copy of a Nichiren inscribed Gohonzon and chant the seven character Daimoku. You become more like Shakyamuni Buddha and Nichiren Daishonin and less like Nichikan and Daisaku Ikeda.
