As Yin gazed in fear-stricken amazement, a knowledge of the various Pure Ones who composed the assembly came upon him. He understood that the three unclad and commanding figures which stood together were the Emperors of the Heaven, Earth, and Man, whose reigns covered a space of more than eighty thousand years, commencing from the time when the world began its span of existence. Next to them stood one wearing a robe of leopard-skin, his hand resting upon a staff of a massive club, while on his face the expression of tranquillity which marked his predecessors had changed into one of alert wakefulness; it was the Emperor of Houses, whose reign marked the opening of the never-ending strife between man and all other creatures. By his side stood his successor, the Emperor of Fire, holding in his right hand the emblem of the knotted cord, by which he taught man to cultivate his mental faculties, while from his mouth issued smoke and flame, signifying that by the introduction of fire he had raised his subjects to a state of civilized life. On the other side of the boundless chamber which seemed to be contained within the rocks were Fou-Hy, Tchang-Ki, Tcheng-Nung, and Huang, standing or reclining together. The first of these framed the calendar, organized property, thought out the eight Essential Diagrams, encouraged the various branches of hunting, and the rearing of domestic animals, and instituted marriage. From his couch floated melodious sounds in remembrance of his discovery of the property of stringed woods. Tchang-Ki, who manifested the property of herbs and growing plants, wore a robe signifying his attainments by means of embroidered symbols. His hand rested on the head of the dragon, while at his feet flowed a bottomless canal of the purest water. The discovery of written letters by Tcheng-Nung, and his ingenious plan of grouping them after the manner of the constellations of stars, was emblemized in a similar manner, while Huang, or the Yellow Emperor, was surrounded by ores of the useful and precious metals, weapons of warfare, written books, silks and articles of attire, coined money, and a variety of objects, all testifying to his ingenuity and inspired energy. These illustrious ones, being the greatest, were the first to take Yin’s attention, but beyond them he beheld an innumerable concourse of Emperors who not infrequently outshone their majestic predecessors in the richness of their apparel and the magnificence of the jewels which they wore. There Yin perceived Hung-Hoang, who first caused the chants to be collected, and other rulers of the Tcheon dynasty; Yong-Tching, who compiled the Holy Edict; Thang rulers whose line is rightly called “the golden,” from the unsurpassed excellence of the composed verses which it produced; renowned Emperors of the versatile Han dynasty; and, standing apart, and shunned by all, the malignant and narrow-minded Tsing-Su-Hoang, who caused the Sacred Books to be burned.
