The eight directions are the basis of vaasthu, or traditional architechture. Heat and cold are basic concepts that decide the properties of food and medicine. Discourse is based on these concepts. So an understanding of these is essential to engage with the ideas.
A Telugu medium government textbook defines directions as eight and months as Telugu months. English medium textbooks define directions as four as in the western paradigm, and never mention the Indian months. Vernacular education is more in sync with local paradigms. With loss of the vernacular medium, there will also be a loss of validity of vernacular knowledge.
