The Long Āgama Sūtra 30.14

30.14

佛告比丘：「今此大地深十六萬八千由旬，其邊無際，地止於水，水深三千三十由旬，其邊無際，水止於風，風深六千四十由旬，其邊無際。比丘！其大海水深八萬四千由旬，其邊無際，須彌山王入海水中八萬四千由旬，出海水上高八萬四千由旬，下根連地，多固地分，其山直上，無有阿曲，生種種樹，樹出眾香，香遍山林，多諸賢聖，大神妙天之所居止。其山下基純有金沙，其山四面有四埵出，高七百由旬，雜色間廁，七寶所成，四埵斜低，曲臨海上。

The Buddha told the monks, “Now, this Earth is 168,000 yojanas deep, and its bounds are endless [in the four directions]. Where the earth stops, there’s water. The water is 3,030 yojanas deep, and its bounds are endless. Where the water stops, there’s air. The air is 6,040 yojanas deep, and its bounds are endless.

“Monks, the ocean’s water is 84,000 yojanas deep, and its bounds are endless. Sumeru the mountain king is 84,000 yojanas in the water, and it rises to a height of 84,000 yojanas above the ocean. Below, it’s roots connect it to the earth with many hard points. That mountain goes straight up without any bends. All sorts of trees grow on it, and the trees produce many fragrances. The fragrances pervade the mountain’s forests. Many noble people, great spirits, and marvelous gods make their homes there. The foundation under that mountain is entirely gold sand. Four crags emerge from that mountain’s four sides that are 700 yojanas high with a mixture of colors throughout and made of the seven treasures. Those four crags are slanted, leaning precariously over the ocean.
