Legilimency is a magical skill in the Harry Potter universe that allows a witch or wizard to read another person's thoughts and emotions. This ability can be used to gain insight into a person's mind, uncover secrets, or even influence their feelings. It requires a strong mental focus and is often depicted as a complex and challenging practice. Practitioners of Legilimency can delve into the memories and feelings of others, but it is considered an invasive skill. The use of Legilimency is often associated with dark magic, especially when used without consent, as it can violate a person's privacy and autonomy.
