The term Anitya (अनित्य), in the sense of impermanence of objects and life, appears in verse 1.2.10 of the Katha Upanishad, one of the Principal Upanishads of Hinduism [REF].
Buddhism and Hinduism share the doctrine of Anicca or Anitya, that is "nothing lasts, everything is in constant state of change"; however, they disagree on the Anatta doctrine, that is whether soul exists or not [REF].
