Producers want us to consume. Science never rests in expanding the boundaries of knowledge. We want to be passionate because passion drives us toward our goal. If we can energize ourselves we can accomplish those things that we believe will make us happy. Unfortunately, as we chase our desires we may find ourselves on a treadmill.
Desire arises and is either frustrated or fulfilled.
If fulfilled, it is followed by another desire. If unfulfilled, it leads to dissatisfaction and more striving. Equanimity implies mental balance and wisdom. When we attain equanimity we may pursue our desires, but we are not overwhelmed with disappointment when they are foiled. When evil prevails we know this is temporary.
