We need to attach a reason to our emotional states. At the high end of the emotional spectrum, we believe that true joy is an effect rather than a cause. Because of this deep-seated belief, we spend most of our lives chasing whatever we think causes the effect of joy -- it may be a perfect relationship, lots of money, fame, the perfect place to live, even our God. At the low end of the emotional spectrum, the game we play is blame. We blame anything from the food we have just eaten to our partners to the government for the reason that we feel bad.

The intuitive mind is a sacred gift and the rational mind is a faithful servant. We have created a society that honors the servant and has forgotten the gift.

- Albert Einstein

Man has been endowed with reason, with the power to create, so that he can add to what he's been given. But up to now he hasn't been a creator, only a destroyer. Forests keep disappearing, rivers dry up, wild life's become extinct, the climate's ruined and the land grows poorer and uglier every day. [Uncle Vanya, 1897]
