Here's why:
* Hinduism is a diverse religion: It's practiced by people across the world, speaking a wide variety of languages.
* Sanskrit is the sacred language: Though Sanskrit is the language of many ancient Hindu scriptures, it's not spoken as a primary language by most Hindus today. It's primarily used in religious ceremonies and rituals.
* Regional languages are important: Hindus in India and other parts of the world use their local languages for everyday life, including worship and religious gatherings.
So, instead of a single language, you can think of Hinduism being practiced in hundreds of languages around the world.
