Or as in the To the Moon (TTM) version of the Bible– “Love is never unsuccessful” (see my last post) is not only biblically true – it is true in the magical world of Harry Potter. According to Wikipedia:
Magic and love
Arguably the most powerful form of magic is also the most mysterious and elusive: love. Lord Voldemort, having never experienced love himself, underestimates its influence—to his detriment. It was through love that Lily Potter was able to save her son Harry from death by sacrificing her life so that he might live. The exact nature of how “love-magic” works is unknown; it is studied in-depth at the Department of Mysteries.
