I want to work in theater drama most probably in marathi theater. what do i do for this.Is there any clases or workshop.

There are usually acting workshops or classes everywhere, just check where they are in your local area. You should also keep your ears open for open casting calls or even community theatre. Community theatre may not pay anything but it gives you experience and you never know what directors might be watching.
