Nichiren Buddhism is called a “positive religion” because the Lotus Sutra instructs us to confront reality positively, and improve our lives by making efforts with faith. Generally, this world is spoken of negatively, and is called a degraded and disordered world. However, Nichiren Buddhism is different. Even though this world seems like it is degraded, and a world filled with deep desire, we are Buddha’s children. We all have Buddha’s nature, as a seed, waiting to become a Buddha and to construct an ideal world, the “Buddha’s world.” Unfortunately, it is difficult to recognize this nature by oneself, even if it is a part of our own mind.
