The pursuit of happiness is universal. Most of us would like to experience more joy and elation. But when we feel like we are falling short of this ideal, we can often feel downcast. We may even see 'darker' emotional states, from sadness and anger to envy and anxiety, as character defects or serious illnesses. In fact, there is unexpected value in the emotions most of us see as 'negative'. In subtle ways, the more negative emotions can bring us to a richer state of wellbeing. For example, sadness can open our hearts to the fragile beauty of life, enabling us to appreciate what we would usually take for granted. While anger may seem unpleasant, if channelled well, it can be a great catalyst for change and improvement in society. THE POSITIVE POWER OF NEGATIVE EMOTIONS shows how the darker states of emotion are vital to a better understanding of ourselves and a more fulfilled life.
