A quote by Lao Tzu

   Mastering others is strength;
   mastering yourself is true power."

Wisdom by Dalai Lama

The present Dalai Lama, when asked what surprised him most about humanity answered:
" Man, because he sacrifices his health in order to make money. Then he sacrifices money to recuperate his health. And he is so anxious about the future that he does not enjoy the present, the result being that he does not live in the present or the future; he lives as if he is never going to die, and then dies having never really lived."
