These are excellent questions. Thank you.

Salvation is consciously knowing and experiencing that you, fundamentally, are the Creator. All that is. Liberation, if you will.

Hell and "Eternal Damnation" are essentially the most likely experiential outcomes of you "living your life" if you fail to realize that it is you that is responsible, creatively, for All that is. Nihilism, loss of hope, meaning, value, purpose; these are Hell. These are the things to which you are Eternally Damned if you give up on your search for conscious reunification with the Creator.
