How does Charles Wallace resist to hypnotized?

In "A Wrinkle in Time" by Madeleine L'Engle, Charles Wallace resists being hypnotized by using his strong will and intellect. He relies on his deep connection with his family, particularly his love for Meg, to maintain his sense of self. Additionally, he focuses on his own thoughts and emotions, which helps him break free from the influence of IT, the malevolent force attempting to control him. This inner strength ultimately empowers him to reject the hypnotic control.
