Answer

If by “Jain God” you mean the Tirthankars, then no — Jain Dharma does not say that all Tirthankars were “Thakur” before becoming Jain.

In Jainism, Tirthankars are not “Gods” in the creator sense. They are liberated souls who attained Keval Gyan and then Moksha.

Explanation

Most Tirthankars were born in royal or noble families, especially in the Kshatriya tradition. For example:

• Bhagwan Rishabhdev was a king before renunciation.
• Bhagwan Parshwanath was born as a prince.
• Bhagwan Mahavir was born in a Kshatriya royal family.

But calling all of them “Thakur” is not a standard Jain teaching. “Thakur” is a social or regional title, while Jain Dharma focuses on the soul’s purity, not caste or title.

Spiritual Understanding

In Jain Dharma, greatness does not come from birth, caste, or social status. It comes from:

• Right Faith
• Right Knowledge
• Right Conduct
• Renunciation
• Destruction of karma

A soul becomes worthy of worship by conquering attachment, anger, pride, deceit, greed, and karma.

Takeaway

Jain Tirthankars were spiritually great because they conquered themselves, not because of any caste or title like “Thakur.”
