Avyaah –“Vyaya” means destruction; destruction cannot be without change; therefore, that which is “without destruction” (Avyayah) is the changeless. The Indestructible, and therefore, changeless, can never have any modifications (Parinaama). For, modification is but the death of a previous condition and the birth of a new condition. The Eternal and the Immutable (Avyayah) is the Supreme Sat-chit- aananda, and every other thing and being come under the hammer or change. The medium in which all these changes are sustained is Brahman, the Immutable. The Upanishads glorify Him as “Ajaro Amaro Avyayah”-without old age, death or change.
