And all those persons of various orders who then sought the protection of that god are known as his powerful Brahmana followers. And rising from his seat, that mighty god allayed the fears of all those people, and then drawing his bow, he discharged his arrows in the direction of the White Mountain. And with those arrows the hill Krauncha, the son of Himavat, was rent asunder. And that is the reason why swans and vultures now migrate to the Sumeru mountains. The Krauncha hill, sorely wounded, fell down uttering fearful groans. And seeing him fallen, the other hills too began to scream. And that mighty being of unrivalled prowess, hearing the groans of the afflicted, was not at all moved, but himself uplifting his mace, yelled forth his war-whoop. And that high-souled being then hurled his mace of great lustre and quickly rent in twain one of the peaks of the White Mountain. And the White Mountain being thus pierced by him was greatly afraid of him and dissociating himself from the earth fled with the other mountains. And the earth was greatly afflicted and bereft of her ornaments on all sides. And in this distress, she went over to Skanda and once more shone with all her might. And the mountains too bowed down to Skanda and came back and stuck into the earth. And all creatures then celebrated the worship of Skanda on the fifth day of the lunar month.
