"Then, O Brahmana, out of the deep came a tremendous roar like unto the roar of the clouds at the Universal Dissolution. Diverse aquatic animals being crushed by the great mountain gave up the ghost in the salt waters. And many denizens of the lower regions and the world of Varuna were killed. Large trees with birds on the whirling Mandara were torn up by the roots and fell into the water. The mutual friction of those trees also produced fires that blazed up frequently. The mountain thus looked like a mass of dark clouds charged with lightning. O Brahmana, the fire spread, and consumed the lions, elephants and other creatures that were on the mountain. Then Indra extinguished that fire by pouring down heavy showers.
