In a lot of movies I watched and fantasy books I read, the hero always has to save the whole world from some evil ennemy.
The truth is everyone is the hero, and the evil ennemy is our own animal minds.
Your mind is just a part of your body, which is the temporary home of your spirit.
To save your world, you have to turn your ennemy into your best friend : be honest with yourself and learn the truth of life (the way the evidence say life works).
Once you start to seek the truth of life, your mind become rational, helpful.
This is what Jesus meant by loving your ennemy.
Your true self is your spirit, your essence, your consciousness. Your true nature is not an animal nature, it is life itself. What religions call God is you and everything alive (conscious) in the universe.
What connects us to life and each others is our spirits.
We just have to turn our animal minds into the servent our spirits.
You do not depend on anyone. If you can fully open your mind you will overcome its animal nature and become a spiritual being forever. You will still have mortal bodies, but you will have total awarness of life and fulfillment forever.
It is a personal (lonely) path, but you are not really lonely because life is always here now with you.
