What is a change that will last forever?
There is only 1 thing, which is actually no thing, that is permanent and unchanging, that is awareness.
That shared aspect of each of us that is aware of the world, the body, the mind, and all senses.
That clear, pure awareness. The part of you that has been the exact same from the time of your birth up to now.
That is the only unchanging, ever present, always and already here and everywhere you are, clear, pure, awareness. 🙂
