“Happiness is a butterfly, which when pursued, is always just beyond your grasp, but which, if you will sit down quietly, may alight upon you.”

Simplified Meaning:

Happiness is like a butterfly. When you chase after a butterfly, it keeps flying away from you. But if you stay calm and still, the butterfly might come and sit on you by itself. This means that if you are always trying too hard to find happiness, you may not get it. However, if you stay relaxed and live your life without stressing too much about being happy, happiness may come naturally to you. For example, imagine you really want to make a new friend. If you're too eager and pushy, people might feel uncomfortable and keep their distance. But if you are friendly and open, without being in a rush, you might find that friendship happens more easily. So, the advice is to not be too desperate in your search for happiness but to let it come to you while you enjoy the present moment.
