The principle of responsive communion is very important in Nichiren Buddhism. To use an analogy, when talking on the phone, if the connection is good, we’ll be heard even if we speak softly, but if it’s bad, then sometimes the other person won’t be able to hear us even if we shout. In order for our prayers to be effective, we need to express them honestly and directly to the Gohonzon.
