That type of permanence, which has the nature of undergoing change. For example, the soul will ever remain soul; from this point of view, it is permanent. The modes of the soul undergo changes; from this point of view, it is impermanent or changing. This is Pariṇāmīnityavāda (the doctrine of 'persistence-through-change') propounded in the Jain philosophy.
