Lu Ya the Taoist priest had calculated and discovered that Xuan Ming had revived and was looking to reclaim his own body, so he communicated with Buddha Great Sun Tathagata, who dispatched the top expert of the esoteric sect, Tsangyang Gyatso, to intercept Wukong in the midst of his journey. The esoteric sect's foundation was too shallow compared to the exoteric sect, and they simply couldn't be mentioned in the same breath. Therefore, the exoteric sect had boundless Bodhisattvas and three thousand Buddhas, while the esoteric sect had this one and only Primordial Golden Immortal.
This Tsangyang Gyatso was of no ordinary background, having already reincarnated six times, and it was said that after nine reincarnations, one could attain the supreme path—though whether this was true remained to be seen.
