"You've always had the power my dear, you just had to learn it for yourself." - Glinda, the good witch, The Wizard of Oz. Wow if we would learn that our power is from God and we already have it? How powerful we would be!
In this picture, a house falls on one of the witches. This is a example of how magic is involved with the wizard or OZ. In reality, it would be impossible for a house to lift up and fall on a person. But in the wizard of Oz, its possible.
