Short, clear answer from Jain viewpoint:

1. About “next Tirthankar – new era”

- We are in the current Avasarpini (descending half‑cycle). - In this half‑cycle, all 24 Tirthankars have already come, the last being Bhagwan Mahavir. - No more Tirthankars will be born in this same half‑cycle. - The next set of 24 Tirthankars will arise only in the next Utsarpini (ascending half‑cycle), after an unimaginably long time.

1. Will “all of us” be reborn again in that next era?

- Jain dharma never says that the same set of current people will automatically take birth again for a fixed number of lives like “7 births” in the time of the next Tirthankars. - Every jiva (soul) is eternal and individual, and its future births depend only on its own karma, not on a fixed rule like “everyone gets 7 more births.” - Some souls may, by their karmas, reach next eras, some may go to heavens, hells, animal, human etc., and some may even attain moksha long before that future era. - So the idea that all of us will definitely be reborn again for exactly seven births in the time of the next Tirthankars is not a Jain scriptural teaching. It is more like a popular saying or confusion, not a siddhant.

1. What does Jain siddhant actually emphasize?

- Your next birth depends on your current beliefs, thoughts, speech and actions. - If you follow samyak darshan, samyak jnan, samyak charitra and reduce your kashayas (anger, pride, deceit, greed), you can: - get better future births, or - even move towards moksha, not keep wandering in fixed cycles like “7 births.”

So, according to Jain dharma:

• Yes, new Tirthankars will come in the next era, but
• No, there is no rule that all of us now will again take 7 births in that new era. Each soul’s journey is independent and karma‑based.
