Learn how to do the ritual that Zelda used, and use it on her.

Of course! If Link did that ritual on Zelda, she'd want to join in the fun too! Great idea, Link. Why thank you, Link.

Teleporting around Castle Town, Link found herself in Zelda's study, and found that the spellbook with the ritual and all the components she had used for it before were right there! Perfect! Not only that, but she could read the language of the book now, and easily perform it! The idea put a sharp-toothed smile on Link's face.

Zelda, it turned out, was still fast asleep in her own bed, so Link quietly set up the magic circle around her, and just as she was beginning to wake up, her eyes looking confusedly around her room, Link activated the spell.
