throughout the whole extent of their mountains, rivers, and seas; and the earth, bare of verdure and destitute of moisture, alone remains, resembling in appearance the back of a tortoise. The destroyer of all things, Hari, in the form of Rudra, who is the flame of time, becomes the scorching breath of the serpent Sesha, and thereby reduces Patala to ashes. The great fire, when it has burnt all the divisions of Patala, proceeds to the earth and consumes it also. A vast whirlpool of eddying flame then spreads to the region of the atmosphere and the sphere of the gods, and wraps them in ruin. The three spheres show like a frying-pan amidst the surrounding flames, that prey upon all movable or stationary things. The inhabitants of the two upper spheres, having discharged their functions, and being annoyed by the heat, remove to the sphere above, or Maharloka. When that becomes heated, its tenants, who after the full period of their stay, are desirous of ascending to higher regions, depart for the Janaloka." [**]
The "Vayu Purana" [*+] gives more explicit teaching on this subject.
"Those sainted mortals who have diligently worshipped Vishnu and are distinguished for piety, abide at the time of dissolution in Maharloka, with the Pitris, the Manus, the seven Rishis, the various orders of celestial spirits and the gods. These, when the heat of the flames that destroy the world reaches to Maharloka, repair to Janaloka in their subtle forms, destined to become re-embodied in similar capacities as their former, when the world is renewed, at the beginning of the succeeding Kalpa. This continues throughout the life of Brahma; at the expiration of his life all are destroyed; but those who have then attained a residence in the Brahmaloka,
by having identified themselves in spirit with the Supreme, are finally resolved into the sole existing Brahma."
The "Vishnu Purana" [**] continues as follows: "Janarddana, in the person of Rudra, having consumed the whole world, breathes forth heavy clouds. Mighty in size, and loud in thunder, they fill all space. Showering down torrents of water, these clouds quench the dreadful fires which involve the three worlds, and then they rain uninterruptedly for a hundred years and deluge the whole world. Pouring down in drops as large as dice, these rains overspread the earth, and fill the middle region and inundate heaven. The world is now enveloped in darkness, and all things, animate and inanimate, having perished, the clouds continue to pour down their waters for more than a hundred years."
The four Yugas mentioned above--viz. the Krita, Treta, Dvapara, and Kali--have characteristic qualities. The Krita is the golden, and Kali the iron age. The Mahabharata [*+] gives these characteristics very distinctly. Hanuman, the monkey-god, is the speaker, describing the four ages to Bhimasena, one of the Pandus.
