Synopsis Here is the thought-provoking work, which attempts to provide a rational basis to the Jain concept of soul. The nature, structure and functions of the soul cannot be studied without a reference to the physical apparatus. But the independent existence of the spiritual and the physical reality cannot be denied, however close their relationship. The unity and diversity are also important problems that a philosopher cannot ignore. In fact Nagarjuna, Sankara, Hegel, Bradley and others have exercised their brains to understand the conscological problem with reference to them, Dr. Jain has taken all their speculations into account to give a meaningful interpretation to the Jaina concept of the non-absolute which he considers as the fundamental reality of the Jaina system, beyond all theses, drstis and paksas, like the Madhyamika absolute that evades expressibility.
