The Union can play a significant role in promoting the development and spread of the Hindi language as a means of fostering unity and cultural exchange within India's diverse linguistic landscape by following the guidelines provided in Directive for Development of Hindi Language. This includes:

1. Promoting the spread of Hindi language to make it serve as a medium of expression for all elements of the composite culture of India.
2. Developing the Hindi language so that it can express the diverse cultural expressions found within India's various languages and styles.
3. Enriching the Hindi language by assimilating forms, style, and expressions from Hindustani and other Indian languages mentioned in the Eighth Schedule without interfering with its genius.
4. Drawing on Sanskrit for primary vocabulary development, and other languages as a secondary source when necessary or desirable to enrich the Hindi language further.
5. Collaborating with state governments and local bodies to implement policies that support the learning and use of the Hindi language in official communications and education systems across India.
6. Encouraging translation and adaptation of literary works, scientific texts, and other materials from regional languages into Hindi, and vice versa, to promote cultural exchange and understanding among linguistic groups in India.
