Extensive reading or reading for pleasure is an excellent way of getting a lot of "comprehensible input" in a foreign language. Graded readers provide this type of comprehensible input.
Hindi is one of the biggest languages in the world by number of native speakers. Hence this question: are there any graded readers for Hindi? And where can they be found?
Update: Since some answerers misinterpret the question: what I am looking for is a graded reader for extensive reading, i.e. a resource that allows you to acquire vocabulary by reading, not by looking up words or studying vocabulary lists that are provided with the text. A graded reader is not the same thing as a reader for intensive reading, in which texts are accompanied by vocabulary lists. Arranging the texts by order of difficulty does not turn a reader for intensive reading into a graded reader for extensive reading.
