A very good quote from the Dalai Lama

Mentally, physically and emotionally we are the same. We each have the potential to good and bad and to be overcome by disturbing emotions such as anger, fear, hatred, suspicion and greed. These emotions can be the cause of many problems. On the other hand if you cultivate loving kindness, compassion and concern for others, there will be no room for anger, hatred and jealousy.
