However, in the book, Glinda's role is a little more involved. Here's what she says:
* Glinda: *“You’ve been given a great gift, my dear. But you have forgotten the secret of it. Your heart is filled with love, and your shoes are made of silver. Click your heels together three times and say, ‘There’s no place like home!’"*
In the movie, the "silver" shoes are ruby red, but Glinda still emphasizes the importance of Dorothy's own inner strength and love for her home.
