If the room of the soul is not cleaned, it will be full of things. A dusty heart will become gray and confused. We go through many things every day, happy and unhappy, all settling down. When there are too many things in the heart, there will be some painful emotions and unpleasant memories. If the heart is full of them, it will make people feel depressed. Therefore, sweeping the floor can brighten a gloomy heart; clarifying things can help you say goodbye to troubles; throwing away some unnecessary pain can give you more and bigger space for happiness.
