We crave lasting happiness in the midst of change: Our bodies age, cherished objects break, pleasures fade, relationships fail. Our attachment to the good things in life and our aversion to the bad amount to a denial of these realities, and this inevitably leads to feelings of dissatisfaction. Mindfulness is a technique for achieving equanimity amid the flux, allowing us to simply be aware of the quality of experience in each moment, whether pleasant or unpleasant.
