Here's why:
* Focus on Social Reform: Ram Mohan Roy's primary focus was on social reform in India, particularly challenging practices like Sati and promoting education and monotheism. He wasn't known for translating religious texts.
* Language: While Hindi was a prevalent language in some regions, Sanskrit and Persian were more widely used in intellectual circles during his time (late 18th and early 19th centuries).
* Saddharma Pundarika Sutra's Relevance: The Saddharma Pundarika Sutra is a Mahayana Buddhist text, and Ram Mohan Roy's focus was on reforming Hinduism, not promoting Buddhism.
It's important to note that there have been translations of the Saddharma Pundarika Sutra into Hindi by various individuals and organizations over the years. However, attributing this translation specifically to Ram Mohan Roy is incorrect.
