Is three years sahityaratna degree from Hindi sahitya sammelan is recognised degree?

No, a three-year Sahityaratna degree from the Hindi Sahitya Sammelan is not a recognized degree in the same way a university degree is. While it's a respected certificate indicating proficiency in Hindi literature, it's not equivalent to a Bachelor's degree from a recognized university and won't be accepted as such by most employers or higher education institutions.
