My belief has come about in large measure because of the lives and examples of people I have known - not the famous, not saints, but friends and relations who have lived, and faced death, in the light of the Resurrection story, or in the quiet acceptance that they have a future after they die.
Everybody should do in their lifetime, sometime, two things. One is to consider death...to observe skulls and skeletons and to wonder what it will be like to go to sleep and never wake up-never. That is a most gloomy thing for contemplation; it's like manure. Just as manure fertilizes the plants and so on, so the contemplation of death and the acceptance of death is very highly generative of creating life. You'll get wonderful things out of that.
Civilization has evolved toward more acceptance, understanding and tolerance of global thinking. If we accept differences, our creativity booms. It makes life much more colorful. It also makes humanity much more safe. If we see pureness somewhere as something to be desired, the trouble starts.
The strongest and most effective force in guaranteeing the long-term maintenance of power is not violence in all the forms deployed by the dominant to control the dominated, but consent in all the forms in which the dominated acquiesce in their own domination.
To be shocked at how deeply rejection hurts is to ignore what acceptance involves. We must never allow our suffering to be compounded by suggestions that there is something odd in suffering so deeply. There would be something amiss if we didn't.
