More on the basic feeling of lack, which if we do not attend to it, makes us feel as if life is not offering us enough, or that we are not making enough of it:

‘Man. Because he sacrifices his health in order to make money. Then he sacrifices money to recuperate his health. And then he is so anxious about the future that he does not enjoy the present; the result being that he does not live in the the present or the future; he lives as if he is never going to die, and then dies having never really lived’.
