Strange noises are heard proceeding from every point. . . . These are the precursors of the Night of Brahma; dusk rises at the horizon, and the Sun passes away behind the thirteenth degree of Makara (sign of the Zodiac). . . . Gradually light pales, heat diminishes, uninhabited spots multiply on the earth, the air becomes more and more rarefied; the springs of waters dry up, the great rivers see their waves exhausted, the ocean shows its sandy bottom and plants die. Men and animals decrease in size daily. Life and motion lose their force, planets can hardly gravitate in space; they are extinguished one by one, like a lamp which the hand of the chokra (servant) neglects to replenish. Surya (the Sun) flickers and goes out, matter falls into dissolution (pralaya), and Brahma merges back into Dyaus, the Unrevealed God, and, his task being accomplished, he falls asleep. Another day is passed, night sets in and continues until the future dawn.
