When we are confused about the source of happiness, we start to blame the world for our dissatisfaction, expecting it to make us happy. Then we act in ways that bring more confusion and chaos into our life. When our mind is busy and discursive, thinking uncontrollably, we are engaging in a bad habit. We are stirring up the mud of jealousy, anger, and pride. Then the mind has no choice but to become familiar with the language of negativity and develop it further.
When desire or anger takes our mind and says, “You're coming with me,” we become paupers. The pauper wakes up each morning with the thought “What about me? Will I get what I want today?” This meditation resonates through our day like a heartbeat. We think, “Will this food make me happy?” “Will this movie make me happy?” “Will this person make me happy?” “Will this new sweater make me happy?” “What about me?” becomes the motivating force of our activity.
