H.H. The Dalai Lama
"A calm mind is the basic element in being able to utilize our intelligence properly. If our minds are dominated by destructive emotions, then our brain functions will not be normal. As a result, we cannot see reality. There is often a gap between reality and its appearance. Therefore, objective analysis is necessary. A mind dominated by hatred or suspicion makes wrong decisions. Many wrong decisions in the fields of politics have been made because of the inability to see reality as it is."
