• To utilize our human intelligence fully, we need calmness. If we become unstable through anger, it is difficult for us to use our intelligence well. When we are overly influenced by negative thoughts, our intelligence becomes tarnished. Looking at human history over the last few thousand years, and particularly in this century, we see that human tragedies like the holocaust arise from negative emotions such as hatred, anger, fear, and suspicion. And we also see that the many positive developments of human history have all come from good mental states, such as compassion.
