Answer

In Jain tradition, the 24 Tirthankars of the current Avasarpiṇī Chovisi did not all take the same number of previous births before becoming Tirthankars.

However, the exact count of “how many births each Tirthankar took before becoming a Tirthankar” is not commonly given in one uniform, universally accepted list across all Jain traditions.

What is clearly established is:

• Each Tirthankar had many previous births before the final birth in which they became a Tirthankar.
• At some earlier birth, each soul earned Tirthankar-nām-karma.
• After the rise of that karma, the soul takes its final Tirthankar birth and establishes the fourfold Jain Sangh.
• After attaining Kevaljñān and completing their life, the Tirthankar attains Moksha.

Explanation

Jain scriptures and traditional biographies often describe important previous births of Tirthankars, especially where they performed intense spiritual practices, developed compassion, renunciation, equanimity, and earned Tirthankar-nām-karma.

For example:

• Bhagwan Rishabhdev is described with important previous births connected to the soul’s gradual spiritual rise.
• Bhagwan Shantinath, Kunthunath, and Aranath are traditionally remembered also as Chakravartis in previous spiritual contexts.
• Bhagwan Neminath and Bhagwan Mahavir have well-known previous-birth accounts in Jain tradition.

But giving an exact numerical table for all 24 Tirthankars requires a specific accepted textual source. Without that, it would not be proper to present a fixed number as certain.

Spiritual Understanding

The main Jain teaching is not merely the number of births, but the principle that:

• A soul becomes great through right faith, right knowledge, and right conduct.
• Tirthankarhood is the result of extremely pure compassion, austerity, equanimity, and spiritual leadership karma.
• Even the highest worldly and heavenly births are still within saṁsār until Moksha is attained.

Takeaway

Sorry, I can only provide information that is clearly established within Jain tradition. The exact number of previous births for each of the 24 Tirthankars is not something I should list unless tied to a verified traditional source.
