What was the spark for india’s cultural revival? what are some examples of it?

India's cultural revival was sparked by a couple of things. Because of British influence after it's colonization and because of urbanization and polarization, a movement started that would bring back India's vast cultural heritage. Examples of bringing it back are exploring folk art and traditional practices, such as religious practices and looking at the philosophical and mathematical achievements of Indian Greats. It is important to note that this is a new movement and has just come about with the rapid exodus of Indian peoples and new technological advances.
