Other schools of Buddhism often focus on the parables and other teachings of the theoretical section in the hope that, through their own practice, they will see for themselves the truth expressed in the Original Gate. In Nichiren Buddhism, the Original Gate is held to be primary because our practice is based on our faith in the active presence of the Buddha in the form of Namu Myoho Renge Kyo. Through upholding the Lotus Sutra by chanting Namu Myoho Renge Kyo, we become one with the Eternal Buddha. The difference lies in whether we rely upon the future possibility of attaining Buddhahood taught in the theoretical section, or upon our present ability to actually attain Buddhahood through faith in the Eternal Buddha, as taught in the essential section.
