Jivatva (Sanskrit: जीवत्व) means – the state of life or the state of the individual soul. Jivatva is the state of life of the Jiva (transmigratory individual soul), the living entity, which is a particular manifestation of Atman, the embodied being limited to psycho-physical states, and the source of avidya that suffers (repeated) transmigration as result of its actions. Until ignorance ceases the Jiva remains caught in experience of the results of actions bringing merit and demerit, and in the state of individuality (jivatva) ( Brahma Sutra I.iv.6), and so long as the connection with the intellect as conditioning adjunct lasts, so long the individuality and transmigration of soul lasts (Brahma Sutra II.iii.30).
