Early one morning, glancing at the starry heavens, Gautama had a profound experience. “Aha! I’ve found you! Never again will I be deceived!” he exclaimed, as much with utter joy as complete exhaustion. What did he find? Whatever it was, it converted him from “ignorance” to “Enlightenment.” Different responses as to what he saw and understood have been given by various schools, all of them believable. One was the “twelvefold chain of dependent origination,” a profound understanding of the completely interwoven nature of all reality and the inexorable role of causality in tying them all together—all of which conspire to inevitably cause suffering when driven by grasping. Another was the three marks of existence itself (impermanence, suffering, and selflessness) and the eightfold way to end their hold on the human being. According to Zen, Gautama had a profound satori, a deep awakening experience, awakening to his own true Buddha-nature and his fundamental oneness with the entire Ground of Being (or Dharmakaya), ending his separate-self sense, and with it, suffering. Whatever exactly it was, it did indeed soon become formalized in the three marks of existence, the twelvefold chain, and the eightfold way. Gautama Siddhartha had sat down under the Bodhi tree an ordinary individual and got up from it an Enlightened or Awakened being, a Buddha. When Buddha was asked if he was a God or supernatural being, he replied, “No.” “What was he?” “Awakened,” is all that he replied.
