Luke Skywalker (to Grogu): I want to tell you about someone you remind me of a great deal. His name was Yoda. He was small like you, but his heart was huge, and the Force was strong in him. He once said to me, “Size matters not.” That’s how he talked. He would speak in riddles.

From The Book of Boba Fett – Season 1 Episode 6: ‘Chapter 6: From the Desert Comes a Stranger’ (1×06) | Produced by Lucasfilm & Disney+
