In Jain cosmology, Jambuswami is considered the last kevali of the present half-cycle (avasarpini). The next Tirthankara will appear in the next half-cycle (utsarpini) and that Tirthankara is Prabhava. So, there is no “next” Tirthankara after Jambuswami within the current cycle—the future Tirthankara will come in the next cycle. Different Jain traditions agree on the basic sequence, though dates and details can vary between Digambar and Śvetāmbara sources.
