Sir William Jones said, "The Sanskrit language, whatever be its antiquity, is of a wonderful structure; more perfect than the Greek, more copious than the Latin, and more exquisitely refined than either, yet bearing to both of them a stronger affinity, both in the roots of verbs and in the forms of grammar, than could have been produced by accident; so strong, indeed, that no philologer could examine them all three, without believing them to have sprung from some common source, which, perhaps, no longer exists."
I think considering what the Linguistics experts such as Sir William Jones have said on Sanskrit, and its comparison with Ancient Greece and Latin, and the implied inferior status of other IE Languages, in terms of its richness of grammar and copiousness, it is fair for CBSE to force KVs to adopt, once again, the Sanskrit Language, which is our National Treasure.
There is a plethora of books in Sanskrit which one does not get chance to encounter in the Westernized Style Education but important for people who would like to know and learn more about Ancient India.
I think the Sonia led UPA Govt has clearly shown apathy to anything that is culturally linked to the Vedic Aryans. Her world is centered around the Latin and Anglo Saxon World. English is basically a combination of Germanic, Latin and Nordic/Norse words.
