Oh dear ... I'm afraid you've got a lot more research to do.
Aviation is governed by a civil aviation authority in every country - in your case, the DGCA in India. These authorities regulate the industry and are responsible for issuing the licences. Licences from one country are not necessarily valid in another.
Therefore, in order to have an Indian licence, you either train in India or you convert from another country's licence. You need to find out from your country's aviation authority (Google DGCA India) what is required to convert from say, either FAA, CASA, JAA to an Indian licence).
