In Jainism, nirvāṇa (moksha) is the final liberation of a soul from all karmic bondage. Nigodas are described as the most primitive beings in the cosmos—innumerable, very basic life-forms that possess only a minimal form of life and are deeply bound by karma. Here’s the key idea about nigod life and how nirvāṇa would relate to them:

• Nigods are not independent “path-makers” for their own liberation. They live under the same universal law of karma as other beings, but their form of life is so rudimentary that they cannot consciously undertake spiritual practices.
• Liberation (nirvāṇa) is achieved by a soul through right faith, right knowledge, and right conduct, which involve deliberate ethical discipline, self-control, and the shedding of karmic residue via ascetic or virtuous living. A nigod, being very limited in perception and capability, cannot pursue these steps on its own.
• In Jain cosmology, it is the enlightened beings (Tirthankaras and other liberated souls) who teach, inspire, or support others on the path, and it is through the gradual accumulation and shedding of karma by beings who can practice austerities and right conduct that any soul—eventually—can progress toward moksha. Nigodas, due to their highly constrained nature, are not described as achieving nirvāṇa on their own through “nigod tapas.”
• The spiritual essence of nirvāṇa remains the same for all souls: complete purification, shedding all karma, and permanent freedom from rebirth. For nigodas, liberation would only come as a result of the universal karma framework guiding all beings toward purification—often understood as a gradual process over countless lives, aided by the presence of fully enlightened beings who illuminate the path.

If you want, I can translate or explain a specific Jain sutra or stotra that discusses karma, bondage, and moksha in a way that relates to nigodas, staying within the Digambara/Shvetambara nuances.
