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.
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.
Too much openness and you accept every notion, idea, and hypothesis-which is tantamount to knowing nothing. Too much skepticism-especially rejection of new ideas before they are adequately tested-and you're not only unpleasantly grumpy, but also closed to the advance of science. A judicious mix is what we need.
Everything is already perfect. And if you can accept that everything is already perfect, the imperfection is a part of the perfection. What's to worry about?
Buddha's doctrine: Man suffers because of his craving to possess and keep forever things which are essentially impermanent...this frustration of the desire to possess is the immediate cause of suffering.
