I believe the ultimate aim of all human beings is to obtain happiness and a sense of fulfillment... I have always stressed the importance of combining both the mental and material approach to achieving happiness for humankind.
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.
Lack of understanding of the true nature of happiness, it seems to me, is the principal reason why people inflict sufferings on others. They think either that the other's pain may somehow be a cause of happiness for themselves or that their own happiness is more important, regardless of what pain it may cause. But this is shortsighted. No one truly benefits from causing harm to another sentient being. . . . . In the long run causing others misery and infringing their rights to peace and happiness result in anxiety, fear, and suspicion within oneself.
