The length and breadth of the mountain are of the same measurement [eighty thousand miles]. Its three principal peaks, which are made of iron, silver and gold, beautify all directions and the sky. The mountain also has other peaks, which are full of jewels and minerals and are decorated with nice trees, creepers and shrubs. The sounds of the waterfalls on the mountain create a pleasing vibration. In this way the mountain stands, increasing the beauty of all directions.
