According to Jain tradition and scriptures, all 24 Tirthankaras of the current time cycle (Avasarpini) were indeed born in the region known today as India, specifically in areas corresponding to ancient Bharat Kshetra. Jain philosophy explains this as a result of cosmic time cycles and the spiritual conditions present in different parts of the universe.

Jainism describes the world as divided into various regions (Kshetras) where the conditions for spiritual progress and the emergence of Tirthankaras are most favorable. Bharat Kshetra is considered particularly auspicious in the current era for the manifestation of Tirthankaras, due to its unique combination of karma, environmental, and social factors.

However, Jainism teaches that its core principles—Ahimsa (non-violence), Satya (truth), Aparigraha (non-possession), and others—are universal and applicable to all living beings, regardless of geography. The message of the Tirthankaras is meant for all sentient beings, not limited by region or culture. In different time cycles and eras, Tirthankaras may appear in other regions or even in other universes, as described in Jain cosmology.

In summary, while historical Tirthankaras of this cycle were born in India, Jainism’s teachings are universal, and the location is seen as a result of specific karmic and cosmic circumstances, not a limitation of the religion’s universality.
