Well, have you ever heard of two different groups of people who might look different on the outside but share the same beliefs and practices on the inside? That's what we call "desi Jews."
Desi is a word that usually refers to people from India or nearby countries, and Jews are a group of people who follow a religion called Judaism.
So "desi Jews" are people who have roots or heritage from South Asian countries like India, Pakistan, or Bangladesh, but also follow the Jewish religion. They might speak different languages, eat different foods, or wear different clothes than other Jews, but they still share the same important beliefs and traditions.
Just like there are different types of Christians or Muslims with distinct cultures and customs, there are also different types of Jews with their own unique histories and practices. So "desi Jews" are just one particular group within the larger Jewish community, but they are just as valid and important as any other group!
