In Jainism, Jambudweep (also spelled Jambudvipa) is a fundamental concept in Jain cosmology. It refers to the central continent of the universe, as described in Jain scriptures. Here is a detailed explanation:

Meaning and Structure

• Jambu refers to the Indian blackberry tree (Syzygium cumini), which is said to grow at the center of this continent.
• Dweep means 'island' or 'continent'.

Place in Jain Cosmology

According to Jain cosmology, the universe (Loka) is divided into three parts: the upper world (Urdhva Loka), the middle world (Madhya Loka), and the lower world (Adho Loka). Jambudweep is situated in the middle world (Madhya Loka).

Features of Jambudweep

• Shape: Jambudweep is depicted as a circular continent with a diameter of 100,000 yojanas (an ancient measure).
• Mount Meru: At the center of Jambudweep stands Mount Meru (Sumeru Parvat), which is considered the axis of the universe.
• Rivers and Mountains: The continent is divided into various regions by rivers and mountain ranges.
• Regions: Jambudweep is divided into several khandas (zones or regions), including Bharat Kshetra, Airavat Kshetra, and Mahavideh Kshetra.
• Bharat Kshetra: This is the region where we currently live, according to Jain belief.
• Mahavideh Kshetra: Another important region where Tirthankaras (enlightened teachers) are always present.
• Civilizations: Human beings and other beings live in Jambudweep, and it is the only continent where souls can achieve liberation (moksha) as Tirthankaras are born here.

Spiritual Importance

• All Tirthankaras who have attained liberation were born in Jambudweep.
• Samavasaranas (divine preaching assemblies of Tirthankaras) are held here.
