The root of suffering is attachment. — Buddha
The root of suffering is attachment.
Author: Buddha
Insight: Most of us think suffering comes from loss or failure—and sure, those hurt. But notice what really twists the knife: it's usually not the event itself, but how tightly we'd wrapped our sense of security around it. We suffer when we're attached to things staying exactly as they are, or people being exactly as we need them to be, or our lives unfolding according to plan. This doesn't mean you shouldn't care about your relationships, your work, or your goals. It means the quality of your attachment matters enormously. There's a difference between loving someone and needing them to be your entire world; between pursuing a career and making it your proof of worth. The first kind of attachment includes a quiet acceptance that things change. The second kind sets you up for crisis whenever reality doesn't cooperate. What's tricky is that attachment often disguises itself as prudence or love. We think clinging harder will protect what we care about. In reality, it usually just tightens the grip of anxiety. When you can hold what matters to you with an open hand instead, something shifts. You're free to actually enjoy it while it's here, rather than constantly bracing for when it might leave.
