Welcome to learning Hindi. Hindi is one of the ancient languages of India. It is derived from India's another language Sanskrit. This has the same Devnagri script as used by Sanskrit.
Hindi is national language of India.
If you want to read Vedas and Upnishads first hand then you must learn Hindi and that will be a good foundation to start learning Sanskrit.
We will start our classes for adults and kids (7 years and up) in West Michigan Hindu Temple, Grand Rapids, Michigan.
I hope that you will enjoy learning this ancient language.
