Ācārya Pūjyapāda defines dhrauvya, as there is neither annihilation nor origination of the inherent nature, it is permanent quality. That is, it is permanent. For instance, clay continues to exist in the lump form, in the pitcher and in its broken parts. So, reality retains its essential nature in the midst of series of changes, which take place in it.
anādipariṇāmikasvabhāvena vyayodayābhāvād dhruvati sthirībhāvatīti dhruvaḥ dhruvasya bhāvaḥ karma vā dhrauvyaṁ. yathā mṛtpiṇda-ghatādyavasthādsu mṛdādyanvāyaḥ.[1]
Thus existence is accompanied by origination, cessation and permanence. The three-fold nature of reality is so interrelated that we can't distinguish them from one another.
