As the Grand Master of the Jedi Order, his power extends to being able to mediate and control “The Force,” which in the greater Star Wars cosmology is a spiritual life force pervading the universe.
Yoda’s species and last name remain unknown, although Lucas originally planned to call him Yoda Minch.
Yoda essentially is an American fictional variant of the Indian guru and, to some extent, the Siberian shaman. Links to these actual religious beliefs and practices shouldn’t be surprising, considering Lucas was friends and consulted with the renowned scholar of religion and mythology, Joseph Campbell.
The fact that the Yoda character has become enshrined in popular culture can hardly be disputed. People even makes jokes about others being “like Yoda” if they’re wise and, perhaps, a bit eccentric.
This attests to the genius of American culture, in particular that of Hollywood. Unlike people in countries clinging to a glorious national past, mythological and otherwise, Americans are creating meaningful myth and culture today.
