* The "Witch" Characters: The three central female figures - Mrs. Whatsit, Mrs. Who, and Mrs. Which - are often described as "witches" by the children. However, they're not practitioners of witchcraft as commonly understood. Their powers are cosmic and based on a higher understanding of the universe.
* Cosmic Powers: The "witches" in the book are more like wise beings with vast knowledge and control over the universe's forces. They travel through time and space, manipulating the fabric of reality. Their powers are based on their connection to a higher power and not on spells or rituals.
* No Magic System: The book doesn't establish a specific magic system or rules for how these powers work. Their actions seem more like a manifestation of their understanding of the universe, rather than a magical practice.
The book explores the themes of:
* Good vs. Evil: The struggle between Meg and Charles Wallace and the evil forces of the Dark Thing.
* Love and Courage: Meg's unwavering love for her brother and her determination to fight against evil.
* The Power of Belief: The importance of believing in oneself and the strength of positive thinking.
So, while "A Wrinkle in Time" might have elements that resemble witchcraft, it doesn't feature traditional witchcraft practices or a magic system. It focuses more on the cosmic battle between good and evil, and the power of love, courage, and faith.
