Chapter XVI is the most important part of the Lotus Sutra for in this chapter is revealed the idea that Buddha is not a person of historical significance. The Buddha is not tied to a physical body who lived and died some twenty-five hundred years ago. The Buddha is not limited to this realm. The Buddha is not the possession of one person only. What is revealed is the eternal nature, the eternally existing, the eternally residing aspect of the Buddha, or as we abbreviate it, the Eternal Buddha. This is not understood in any rational way. It is actually quite unbelievable and, truth be told, logically impossible. Our ever-so-clever minds actually limit our ability to transcend all of this and approach understanding by faith. I believe that understanding the Eternal Buddha is experiential, and that words only talk around the idea. The words in Chapter XVI can lead us to that idea and can help to open the door to understanding by faith because they challenge us to set aside all the rational stuff we are attached to. The words challenge us to, even if for a moment, open ourselves up to connecting with life in a way no book, no computer, no TV show, no sexual experience, or what have you is able to.
