Great Kings of the Past

Mufasa and Simba look at the stars

Mufasa: "Simba... Let me tell you something that my father told me... Look at the stars. The great kings of the past look down on us from those stars."
Simba: "Really?"
Mufasa: "Yes... So whenever you feel alone, just remember that those kings will always be there to guide you ... And so will I."

—Mufasa and Simba

The Great Kings of the Past, according to Mufasa, look down on the living beings from the stars. While it is commonly believed that the lions in The Lion King believe the stars themselves are the great kings of the past, it was never actually confirmed in the film.
