Answer

In Jain Dharma, there are 45 Āgams traditionally accepted in the Śvetāmbara tradition, and they are divided into different groups called kshetras / sections.

If you are asking about Jain cosmology kshetras, then the main karmabhūmi kshetras are:

• 5 Bharat Kshetras
• 5 Airavat Kshetras
• 5 Mahāvideh Kshetras

So total:

15 Kshetras

Explanation

In Jain cosmology, these kshetras are regions where spiritual practice and liberation-related activities can occur.

• Bharat Kshetra – Our present region is one Bharat Kshetra.
• Airavat Kshetra – Similar type of karmabhūmi region.
• Mahāvideh Kshetra – Regions where Tirthankars are always present.

Takeaway

If you mean cosmological kshetras, the total is 15 kshetras.
