Monier Monier-Williams quotes
India though it has more than five hundred spoken dialects, has only one sacred language and only one sacred literature, accepted and revered by all adherence of Hinduism alike, however diverse in race, dialect, rank and creed. That language is Sanskrit and Sanskrit literature, the only repository of the Veda or knowledge in its widest sense, the only vehicle of Hindu mythology, philosophy, law, the mirror in which all the creeds, opinions, and customs and usages of the Hindus are faithfully reflected and the only quarry whence the requisite materials may be obtained for improving the vernaculars or for expressing important religious and scientific ideas.
