Answer

In Jain Dharma, a Nigod jīva and a Nārakī jīva are different states of existence.

A soul that is in Narak is called a Nārakī jīva, not a Nigod jīva while it is there. When a Nārakī jīva completes its lifespan in hell, it leaves Narak and is reborn according to its remaining karma.

It may be reborn in lower life forms such as:

• one-sensed beings,
• plants,
• animals,
• or other non-liberated worldly states, depending on karma.

It does not automatically become liberated, and it does not necessarily become human immediately.

Explanation

According to Jain belief, every worldly soul moves through different births because of karma. A soul may take birth in:

• Narak gati — hellish existence,
• Tiryanch gati — animal, plant, and lower life forms,
• Manushya gati — human existence,
• Dev gati — heavenly existence.

A Nigod jīva is an extremely low and undeveloped form of life, generally understood as a very subtle one-sensed living being. If a soul is born as a Nigod jīva after leaving Narak, it continues in saṃsār with very limited spiritual capacity at that stage.

Spiritual Understanding

The main Jain teaching here is that suffering in Narak does not purify the soul by itself. Liberation comes only through:

• right faith,
• right knowledge,
• right conduct,
• and destruction of karma.

A soul leaving Narak still carries karmas and continues wandering in saṃsār until it gains the proper spiritual opportunity.

Takeaway

A jīva leaving Narak is reborn according to karma. It may enter very low life forms, including Nigod-like existence, but its journey continues until it develops the conditions for right faith, spiritual effort, and ultimately moksha.
