351. Directive for development of the Hindi language.
It shall be the duty of the Union to promote the
spread of the Hindi language, to develop it so that it may serve as a medium of expression
for all the elements of the composite culture of India and to secure its enrichment by
assimilating without interfering with its genius, the forms, style and expressions used in
Hindustani and in the other languages of India specified in the Eighth Schedule, and by
drawing, wherever necessary or desirable, for its vocabulary, primarily on Sanskrit and
secondarily on other languages.
