Juana dragged herself up from the rocks on the edge of the water. Her face was a dull pain and her side ached. She steadied herself on her knees for a while and her wet skirt clung to her. There was no anger in her for Kino. He had said, "I am a man," and that meant certain things to Juana. It meant that he was half insane and half god. It meant that Kino would drive his strength against a mountain and plunge his strength against the sea. Juana, in her woman's soul, knew that the mountain would stand while the man broke himself; that the sea would surge while the man drowned in it. And yet it was this thing that made him a man, half insane and half god, and Juana had need of a man; she could not live without a man. Although she might be puzzled by these differences between man and woman, she knew them and accepted them and needed them. Of course she would follow him, there was no question of that. Sometimes the quality of woman, the reason, the caution, the sense of preservation, could cut through Kino's manness and save them all. She climbed painfully to her feet, and she dipped her cupped palms in the little waves and washed her bruised face with the stinging salt water, and then she went creeping up the beach after Kino.

Juana has a subtle, nuanced understanding of masculinity in the world of The Pearl. According to this interpretation, Kino can’t help fighting against forces larger than himself (like greed and evil) because it’s in his nature as a man.
