Its great to see an app on here focused on encouraging the practice of chanting the mystic law and reciting the sutra. I was raised under the teaching that the Gohonzon should never be photocopied or presented outside of a butsudan, but obviously the teachings regarding this in Nichirens writings are unclear. First and foremost, never seek this Gohonzon outside yourself for it is only a physical manifestation of our life condition.
