Both of them, boundless in might, allying themselves with other classes of beings, fought together, exceedingly exasperated, great in strength and prowess. The Mainā increased in size to two thousand yojanas; as the Heron, O brāhman, increased to three thousand and ninety. And then those two, of wide heroism, assailing each other with blows of their wings, created sore fear among the creatures. The Heron, his eyes swollen with blood, lifting his wings beat the Mainā; and he also, stretching out his neck, struck the Heron with his feet. Overthrown by the wind from their wings, mountains fell down on the earth; and struck by the downfall of the mountains the earth quaked; and the earth, as it quaked, caused the waters of the seas to swell up, and reeled over on one side, turning towards the descent to Pātāla. Living beings perished, some by the fall of the mountains, others by the waters of the seas, others through the quaking of the earth. Thus everything being terrified was turned into lamentation, bereft of consciousness; the world was greatly agitated, and its countries were thrown into confusion, people exclaiming “Ah, my child! ah my beloved child! come, here I am fixed”—“ah my darling wife!”—“my beloved husband!”—“this rock is falling, escape quickly.”
