The line comes from Jujutsu Kaisen, the anime adaptation of Gege Akutami's manga, and is spoken by Yuji Itadori's grandfather in the story's opening arc. As a dying piece of guidance, it sets up Yuji's core belief that a strong person should use that strength to help others, a theme that runs through the whole series. Fans have lifted the short clip for tribute edits, motivational compilations and character studies, where its calm delivery stands out against the show's louder fight scenes and keeps the moment feeling personal rather than dramatic.
