In Jainism, the most exalted (“best”) mountain in Jambudvipa is Mount Meru (also called Sumeru).

• It stands at the very center of Jambudvipa and is revered as the cosmic axis of the middle world (Madhyaloka).
• All Jain traditions honor Meru as the foremost and holiest mountain of Jambudvipa.
• Digambar and Shwetambar texts may differ slightly in numerical measurements of Meru, but both agree that Sumeru is the supreme central mountain.
