Answer

In Jain tradition, the last person of the present time-cycle to attain Keval Gyaan was Jambuswami.

He is regarded as the last Kevali in the current Avasarpini era.

Explanation

Keval Gyaan means perfect, infinite knowledge — the complete and direct knowledge of all substances and their modes.

After Bhagwan Mahavir attained nirvana, the Jain tradition says that the lineage of omniscient beings continued for a short period. The last among them was Jambuswami, who attained Keval Gyaan and later moksha.

Spiritual Understanding

Jambuswami’s life reminds us that liberation is possible through right faith, right knowledge, right conduct, renunciation, and destruction of karmas.

Takeaway

Jambuswami is traditionally accepted as the last living person to attain Keval Gyaan in the present era.
