The story itself is thought to be more than 4,000 years old but is most commonly known for being part of a collection of stories, gathered by the Brothers Grimm in 1812.

In the original, Rumplestiltskin manipulates a helpless young women into giving away her first-born child in return for his talent of spinning straw into gold. He makes a bargain that she can only keep her baby if she can guess his name, which she successfully does, causing him to cause quite a stir before running away forever.

In Calm’s version, Rumplestiltskin “does what any creature famed for their foul temper should do – and learns to meditate” which makes him a “calmer, gentler, more compassionate and benevolent soul.”

Calm says its new version of the story is more than just a piece of whimsy: “the sort of transformation that Rumpelstiltskin undergoes in the new tale is based on scientific evidence of the real effects that meditation can have.”

What’s more, Rumplestiltskin is read by Game of Thrones star Jerome Flynn, which is another reason to give it a listen. “If only Rumpelstiltskin had learnt to meditate as a much younger imp, how differently his story might have turned out,” he says.

Coming up in the series which is available now, is The Wicked Witch of the West Discovers Mindfulness and The Big Bad Wolf Learns Anger Management.
