The nondualistic traditions such as Adi Shankara's Advaita Vedanta tradition of Hinduism champion a monistic premise, asserting that the individual human soul and Brahman are identical, only ignorance, impulsiveness and inertia leads to suffering through Saṃsāra, in reality they are no dualities, meditation and self-knowledge is the path to liberation, the realization that one's soul is identical to Brahman is moksha, and spiritual liberation is achievable in this life ("jivanmukti"). In Jainism, the "Saṃsāra" and karma doctrine are central to its theological foundations, as evidenced by the extensive literature on it in the major sects of Jainism, and their pioneering ideas on karma and "Saṃsāra" from the earliest times of the Jaina tradition. "Saṃsāra" in Jainism represents the worldly life characterized by continuous rebirths and suffering in various realms of existence. The conceptual framework of the Saṃsāra doctrine differs between the Jainism traditions and other Indian religions. For instance, in Jaina traditions, soul ("jiva") is accepted as a truth, as is assumed in the Hindu traditions, but not assumed in the Buddhist traditions. However, Saṃsāra or the cycle of rebirths, has a definite beginning and end in Jainism. Souls begin their journey in a primordial state, and exist in a state of consciousness continuum that is constantly evolving through "Saṃsāra". Some evolve to a higher state, while some regress, a movement that is driven by karma. Further, Jaina traditions believe that there exist "Abhavya" (incapable), or a class of souls that can never attain moksha (liberation). The "Abhavya" state of soul is entered after an intentional and shockingly evil act. Jainism considers souls as pluralistic each in a karma-"Saṃsāra" cycle, and does not subscribe to Advaita style nondualism of Hinduism, or Advaya style nondualism of Buddhism. The Jaina theosophy, like ancient Ajivika, but unlike Hindu and Buddhist theosophies, asserts that each soul passes through 8,400,000 birth-situations, as they circle through "Saṃsāra". As the soul cycles, states Padmanabh Jaini, Jainism traditions believe that it goes through five types of bodies: earth bodies, water bodies, fire bodies, air bodies and vegetable lives.
