It's a set of guidelines for writing short stories, popularized by the Argentine writer Adolfo Bioy Casares. It is not an actual religious document, but a set of rules that Bioy Casares believed would help aspiring writers create engaging stories.
Although the full list is a bit more complex, here is a simplified version of Bioy Casares's "Ten Commandments of the Perfect Storyteller" in English:
1. Start with a good idea. The foundation of a great story is a strong and unique concept.
2. Show, don't tell. Use vivid descriptions and actions to create a picture in the reader's mind.
3. Keep it short and sweet. A good short story gets straight to the point and avoids unnecessary details.
4. Create believable characters. The characters should be relatable and their actions should make sense.
5. Develop a compelling plot. The story needs to be exciting and keep the reader engaged.
6. Pay attention to details. Small details can make a big difference in creating a believable and immersive world.
7. Use vivid language. Use powerful words and imagery to create a lasting impact on the reader.
8. Master the art of suspense. Keep the reader guessing about what will happen next.
9. Create a satisfying ending. The ending should leave a lasting impression and tie up loose ends.
10. Read widely and practice your craft. The more you read and write, the better your stories will become.
It's important to remember that these are just guidelines, and there are always exceptions to the rule. Ultimately, the most important thing is to write what you love and what resonates with you as a writer.
