Quest
We come to Earth to absorb the energy of life. When we do this we take the life-force of the planet and convert it to Spirit energy, which we can take back with us to the Spirit life we left to come to Earth and where we return when our life is ended.
So you see the old adage "You can't take it with you" is not entirely correct. You do take back with you all the white light force you build up on Earth.
This is why it is important to conduct your life in a way where you maximise the amount of energy you generate.
To do this you live life. That is the quest we all are on.
