"一切艺术都是一种忏悔，或多或少是间接的。"

Simplified Meaning:

When someone creates art, like painting or writing a story, they are sharing something personal about themselves, even if they don't do it directly. Think of a song that talks about feeling sad; the songwriter might not say exactly why they are sad, but you can feel their emotions in the music. This is because artists put their own feelings, thoughts, and experiences into their work, like sharing a secret without using words. For example, a painter might use certain colors and shapes to show how they feel about love or heartbreak, without painting an exact scene from their life. Similarly, a movie might tell a story that seems fictional, but it conveys the filmmaker's beliefs, dreams, or fears. People can apply this idea to their own lives by understanding that when they create something, they are expressing themselves. They are allowing others to see a glimpse of their inner world. This can help people connect with others, share their experiences, and even understand their own feelings better.
