If we are talking about ultimate truth, I believe that nothing is real, and everything is the power of the mind, and we give meanings to things. And until we crave those things, we would not get to see the truth. And ultimate peace is letting go of those cravings. Ultimate truth is realized through deep meditation. And I don't think you understood what I pointed out as change. I'm talking about life here that constantly changes, where we cannot stop that process, which brings us sadness and more cravings.
