In Jainism, "Abhavya jiv" (अभाव्य जीव) refers to a category of souls (jivas) that are inherently incapable of attaining liberation (moksha). The word "Abhavya" means "incapable" or "unfit." According to Jain philosophy, all souls have the potential to attain liberation except for abhavya jivas. These souls, due to their inherent nature and past karmic bondage, will never develop the right faith (samayak darshan) and, therefore, will never be able to progress on the path of liberation.

Key points about Abhavya Jiv:

• Definition: Souls that are incapable of attaining moksha, no matter how many births they take.
• Opposite: The opposite of "bhavya jiv," which are souls capable of attaining liberation.
• Reason: Their inherent nature and extremely intense wrong beliefs (mithyatva) prevent them from ever attaining right faith.
• Scriptural References: The concept is discussed in Jain texts such as Tattvartha Sutra (Tattvarthadhigama Sutra) and commentaries by Jain Acharyas.

Summary: Abhavya jiv are those souls which, due to their intrinsic disposition, will never attain liberation, while bhavya jiv are those who have the potential to be liberated.
