In Jainism, Nigod refers to the lowest and most subtle form of living beings.

Meaning

Nigod jīvas are:

• extremely small and subtle,
• present in huge numbers,
• usually in a state of almost complete ignorance and inactivity,
• and often remain in a collective, undeveloped condition.

Main points

• They are considered samsari jīvas in bondage.
• They have very limited consciousness.
• They are found in places like:

- soil, - water, - air, - plants, - and even in the bodies of other living beings, according to Jain doctrine.

• Because of their extremely low state, they have very little ability to move, sense, or think.

Types

Jain texts describe Nigod in two broad ways:

1. Nitya Nigod — beings that have been in the Nigod state from beginningless time.
2. Itara Nigod — beings who fall into Nigod after death from other lower life-forms.

Spiritual importance

Nigod teaches the Jain principle that:

• all jīvas are bound by karma,
• every soul has the potential to evolve,
• and liberation is possible only by right knowledge, right faith, and right conduct.
