Let’s remember that when we sit in front of the Mandala Gohonzon, we are sitting down in a sacred and very spiritual place in order to closely approach the Buddha and Nichiren Shonin. Using a more mundane example, this could be comparable to sitting down to have an important conversation or become closer with someone very special in our lives, such as a good friend, loved one, boyfriend, girlfriend or fiancee. If we meet someone as special as this, then of course we would want to be dressed properly, speak clearly and sincerely, and thoroughly enjoy the time we spend with that person. When we talk to this special person, we will look them directly in the eyes, possibly even feeling great emotion. We will also put all our energy, spirit and attention into addressing that person as we sincerely seek to connect with them. That is, we will use all our heart. It is the same with chanting the Odaimoku.
