In Jainism, there are 24 Tirthankaras (Jin-pratimāji in common speech) in each cosmic half-cycle. These are the 24 great spiritual teachers who have shown the path to liberation. Beyond these 24, Jain cosmology speaks of countless Siddhas (liberated souls) across vast cycles, so the total number of Jinas ever to exist is not fixed—it is innumerable across time.

Key points:

• 24 Tirthankaras are the central, worshipped Jin-pratimāji in this world.
• There are infinitely many Siddhas (Jinas) across past and future cycles.
• Digambara and Śvetāmbara traditions both recognise the 24 Tirthankaras; minor details (such as specific texts or names used in some lists) can differ between sects, but the basic count remains 24.

If you’d like, I can share the list of the 24 Tirthankaras or explain how each is commemorated in temples.
