The Jainas define Jiva or Atman as conscious substance. At man in this world is known as Jiva. It has Prana and physical, mental and sensuous powers. In its pure condition, Jiva has pure knowledge and vision. But due to the effect of Karma, Jiva is yoked with five Bhavasrava viz., Auspasamik, Ksyayik, Ksayo Pasmik, Audayik and Parinamik. Jiva with pudgala is termed as sansri. Jain philosophy is parinamavadin. So bhavas change into dravya and vice. versa.
