Some folks say that the only thing that does not change is change itself.
They foolishly speak that the only thing that is permanent is impermanence.
If you believe this statement, you are believing a falsehood.
In fact, reality is changeless. In your experience, the reality of awareness/consciousness is eternal and changeless.
Thoughts are like clouds and mirages. If you dwell in the mirage, you live in the illusion.
Without the contemplation of the reality of your experience, you are in the grip of the download of the unhappy impression of mortality and separation.
Without complete surrender, you remain in the bubble of the personal self.
