Answer

In Jain tradition, when a nārakī jīva completes its lifespan in hell and is reborn in another realm, there is no commonly established teaching that it emits a special divine light while going upward.

The soul simply leaves that hellish body and takes birth in the next destined gati according to its karmas.

Explanation

According to Jain Dharma:

• A nārakī jīva lives in hell due to intense sinful karmas.
• When its fixed lifespan karma ends, it dies there.
• Immediately, according to its remaining karmas, it takes birth in another state of existence.
• This transmigration happens extremely quickly, without a long journey in the physical sense.

Jain teachings generally describe rebirth as a karmic transition of the soul, not as a visible travel where the soul shines or emits light.

Spiritual Understanding

The important Jain point is not whether a soul emits light while moving, but that every birth is determined by karma. Even a soul from hell may later be reborn in a higher condition if its karmic situation allows it.

This shows that no worldly condition is permanent. The soul’s bondage and liberation depend on karma, conduct, and spiritual purification.

Takeaway

A nārakī jīva does not have a clearly established special-light emission during rebirth in Jain tradition. Its movement to another realm happens by the force of karma, immediately after the end of its hellish lifespan.
