The last half of the sutra, consisting of the latter 14 chapters, is the Essential Section that reveals the Original Buddha. Therefore it is called the Original Gate. In this section, the Buddha personifies the universal and timeless ultimate truth. As such he is known as the Original or Eternal Shakyamuni Buddha. The Eternal Buddha is an ever-present and active spiritual reality that leads all people to realize their own Buddhahood. All Buddhas who appear throughout the universe as teachers in the past, present, and future are reflections of this Eternal Buddha. In other words, they owe their awakening to the Eternal Buddha, their source and model.
