years; and, in consequence of the failure of food, all beings become languid and exanimate, and at last entirely perish. The eternal Vishńu then assumes the character of Rudra, the destroyer, and descends to reunite all his creatures with himself. He enters into the seven rays of the sun 5, drinks up all the waters of the globe, and causes all moisture whatever, in living bodies or in the soil, to evaporate; thus drying up the whole earth. The seas, the rivers, the mountain torrents, and springs, are all exhaled; and so are all the waters of Pátála, the regions below the earth. Thus fed, through his intervention, with abundant moisture, the seven solar rays dilate to seven suns 6, whose radiance glows above, below, and on every side, and sets the three worlds and Pátála on fire. The three worlds, consumed by these suns, become rugged and deformed 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 Śesha, and thereby reduces Pátála to ashes. The great fire, when it has burnt all the divisions of Pátála, 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 shew like a frying-pan amidst the surrounding flames, that prey upon all moveable 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 7.
