九山八海

The nine cakravāla, or concentric mountain ranges or continents, separated by eight seas, of a universe. The central mountain of the nine is Sumeru 須彌 and around it are the ranges Khadiraka 佶提羅, Īṣādhara 伊沙陀羅, Yugaṃdhara 遊乾陀羅, Sudarśaṇa 蘇達梨舍那, Aśvakarṇa 安濕縛竭拏, Nemiṃdhara 尼民陀羅, Vinataka 毘那多迦, Cakravāda 斫迦羅; v. 七金山. The Abhidharma Kośa gives a different order: Sumeru, Yugaṃdhara, Īṣādhara, Khadiraka, Sudarśana, Aśvakarṇa, Vinataka, Nemiṃdhara, with an "iron-wheel" mountain encompassing all; there are also differences in the detail.
