Answer

No. According to commonly accepted Jain tradition, Acharya Bhadrabahu Swami is not generally regarded as having attained Keval Gyan.

He is traditionally remembered as:

• The last Shrut Kevali
• A great Jain Acharya
• A master of the complete scriptural knowledge available in his time

But Shrut Keval Gyan and Keval Gyan are not the same.

Explanation

In Jain Dharma:

• Keval Gyan means perfect, direct, infinite knowledge of all substances and all their modes across past, present, and future.
• Shrut Keval Gyan means complete mastery of the Jain scriptures, especially the vast scriptural tradition such as the Angas and Purvas.

Acharya Bhadrabahu Swami is called the last Shrut Kevali because he had complete scriptural knowledge, especially knowledge of the Purvas.

However, a Kevali is one who has destroyed the knowledge-obscuring karmas completely and attained omniscience. Traditional lists of Kevalis after Bhagwan Mahavir do not usually include Bhadrabahu Swami as a Kevali.

Why Not?

Because scriptural omniscience through study and memory is still different from direct omniscience of the soul.

Acharya Bhadrabahu Swami had extraordinary scriptural knowledge, but Jain tradition does not generally state that he destroyed all ghati karmas and attained Keval Gyan.

So he is honored as a Shrut Kevali, not as a Keval Jnani.

Spiritual Understanding

This distinction is important in Jain Dharma:

• Shrut Gyan comes through scriptures, words, and teachings.
• Keval Gyan arises directly from the purified soul.

Both are deeply respected, but Keval Gyan is the highest form of knowledge.

Takeaway

Acharya Bhadrabahu Swami was a highly revered Jain Acharya and the last Shrut Kevali, but he is not traditionally counted as one who attained Keval Gyan.
