what is universal theme?

A universal theme is a message, lesson or idea that is relevant to all cultures and people throughout history. It is a broad, general topic or concept that can be found in multiple works of literature, art, and music from around the world. Examples of universal themes include love, death, identity, justice, and human nature. These themes are considered universal because they relate to the human experience and are common to all people regardless of ethnicity, culture or time period.

I really don't know, can you be a bit more specific? Thanks.
