Imagine two children in the same class. Both worked hard, but only one of them won the drawing contest. The first child has a jealous heart （嫉妒的心） — small, dark, and tight. It says, “So what? Why not me?” That tight feeling does not take the prize away from anyone; it only makes the jealous child unhappy.
The second child has a Muditā heart （隨喜的心） — bright, open, and growing wider. It says, “Good job! I’m happy for you!” Nothing was lost. The winner is still the winner — but now two children are smiling instead of one. The joy doubled.
This is the secret of Muditā: another person’s success does not make you smaller. Jealousy is a little poison, and Muditā is the antidote （解毒劑）. Before we can be glad for others, we settle our own heart with self-love: I am safe, I am loved, I am happy, I am enough. When you know you are enough, your heart has plenty of room for everyone’s happiness.
