There are three Unforgivable curses causing control over a person, torture or the worst of all, death!
As a matter of fact curses are an integral part of most folklore or mythology or religious tales from Greek and Roman mythology to tales in India to Chinese folklore.
In fact some of the villains of Hindu religious texts like Ravana of the Ramayana are said to have descended on earth to liberate themselves from a curse.
Jaya / Vijaya were two guards to the abode of Vishnu, one of our three important deities and they refused entry to some sages who had the appearance of children. The sages cursed them to be born on earth as mortals. They had a choice to be born 7 times as good pious devout people or as enemies of Vishnu a.k.a the bad guys 3 times. They did not want to be away from the service to Vishnu Bhagawan (Lord Vishnu) for so long and so they chose the latter.
We have stories of people becoming stones, plants, animals, monsters to be later liberated.
In Greek mythology what immediately comes to mind is Medusa and her head of snakes.
Coming to charms, there are quite a few charms in Harry Potter series which I think would be very nice to have in real life.
Oculus Reparo could repair broken glasses with the touch of a wand.
Accio was a summoning charm that could help one to get an object to fly into our arms. That's a Ctrl-F for our home. This would be especially useful with two school going kids that try to remember where they kept their homework just before bedtime. It would definitely go a long way in locating cell phone chargers and ear phones and TV remotes.
There is a hot air charm that would help melt snow along the way to help us walk.
There is a charm to cut vegetables and a charm to stir the soup.
J K Rowling let her imagination go wild and that's what make the stories so very endearing.
Is there anything you would want to accomplish through magic in real life?
