Within each iron wall are four continents, and a sun and moon to shine upon them. It is in the southernmost of these continents, Jambudvipa in the case of our own world, that India and all countries known to the Hindoos are situated. Far to the north is the Sumeru mountain, one million one hundred and twenty thousand miles high, and whose depth in the sea is equally great. It is composed of gold on its east side, of "lapis-lazuli" (lieu-li, spelt in full, according to the old pronunciation, be-lu-li and be-du-li; in Sanscrit, vaiduria ) on the south, of "crystal" (p'o-li, "glass;" in Sanscrit, sp'atika) on the north, and silver on the west.
Travelling south from Jambudvipa across the Southern
ocean, there are three hundred and sixty thousand six hundred and sixty-three "yojanas" (yeu-siun) to the circular mountain mass of iron. This mountain's depth in the sea is three hundred and twelve yojanas, and its height about the same. Its circumference is three million six hundred and ten thousand three hundred and fifty yojanas. Each iron-bound world has a Sumeru mountain in its centre. Supposing the world to be under the eternal law of change sketched above, Buddhist authorities give no account of its first origin, not feeling the need of a doctrine of creation. The physical causes engaged in its periodical formation and destruction are water, wind, and fire. These are three of the four elements ti, shui, hwo, feng, "earth, water, fire, and air," which are supposed to form the basis of all things. They are perhaps to be taken in the sense of elemental causes rather than elemental atoms.
Over and under this world of mountains, seas, and continents are two others, heaven and hell. Of celestial regions there are thirty-two inhabited by the divinities of the older Hindoo mythology. For the Buddhas and Bodhisattwas, peculiar to Buddhism, other abodes are found. Among the thirty-two heavenly regions, ten are called worlds of desire; including, among others, the heaven of the sun and moon, the heaven of the four kings of Devas, and the heaven of the thirty-three or paradise of Indra Shakra, who has under him thirty-three powerful Devas. There are also the Yama paradise, the Tushita paradise, the "Nimala paradise" (Hwa-lo), and the paradise of "Paranimita" (T'a-hwa-tsi-tsai).
At the base of the Sumeru mountain reside shens, "spirits," and Yakshas. Half-way up the mountain is the paradise of the Four kings of Devas. On the summit is the Tau-li or "Trayastrinsha" (thirty-three) heaven,
i.e., the paradise of Shakra, king of the gods. The rest of these celestial abodes are fixed in vacancy, each as high again as the one beneath it.
