In Jainism, "nigod" (sometimes spelled "nigoda") refers to a type of microscopic, one-sensed (ekendriya) living being that resides in a dormant, highly undeveloped state. Nigods are considered to be the lowest form of life in the Jain cosmological hierarchy.

Key points about nigod in Jainism:

1. Definition: Nigods are minute organisms, almost like clusters of infinite souls, which exist in a state of ignorance and have the least development of consciousness. They possess only the sense of touch.

1. Spiritual Significance: According to Jain philosophy, most souls reside in the nigod state for countless ages. Only a few souls get the opportunity to move out of this state and embark on the journey of spiritual evolution.

1. Cosmology: The concept of nigod highlights the vast multitude of souls in the universe and emphasizes the Jain doctrine of transmigration and the potential for liberation for every soul.

1. Types: Jain texts mention two types of nigods:

- Nitya-nigod: Souls that have always existed in the nigod state and have never been embodied in any higher form. - Itara-nigod: Souls that have been in other forms of existence but have returned to the nigod state due to the fruition of their karma.

1. Role in Rebirth: When a living being dies, there is a possibility, according to Jainism, that a soul from the nigod state may take birth in a higher form, while the soul of the deceased may return to the nigod state, depending on karmic conditions.

1. Purpose: The concept of nigod serves to explain the vastness of the soul population and the importance of spiritual development and liberation (moksha) in Jainism.

Thus, nigod represents the beginning and the lowest stage of the soul's journey in the cycle of birth and rebirth, according to Jain beliefs.
