According to Jainism, the earth is not described as a simple globe like in modern maps. It is explained through Jain cosmology as part of the middle world (Madhya Loka).

Main points of the Jain view of Earth:

• The central region of the inhabited world is Jambudvipa.
• In Jambudvipa, there is Mount Meru at the center.
• Around it are seven regions (khetras) and six mountain ranges.
• The world is arranged in a cosmic, symmetrical form, not as a single flat continent or a round planet in the modern sense.
• Jain scriptures describe many layers of existence:

- Urdhva Loka — upper worlds - Madhya Loka — middle world, where humans live - Adho Loka — lower worlds

Simple idea:

In Jainism, “earth” usually means the human realm in Madhya Loka, especially Jambudvipa, which is the central continent of the world system.
