Beyond it (Manasottara Mountain), extending to Lokaloka Mountain, is another land, which is made of gold
SB Canto 5
Beyond the ocean of sweet water is a tract of land as broad as the area between the middle of Mount Sumeru and the boundary of Mānasottara Mountain. In that tract of land there are many living beings. Beyond it, extending to Lokāloka Mountain, is another land, which is made of gold. Because of its golden surface, it reflects light like the surface of a mirror, and any physical article that falls on that land can never be perceived again. All living entities, therefore, have abandoned that golden land.
