So, imagine you know a group of people who have a lot in common - they talk in similar languages, they eat similar foods, and they have similar ceremonies. They also share a lot of artistic and religious beliefs. This is what we call a culture!
Now, in India, there are many cultures like this. Some people may speak Hindi, others may speak Tamil, and so on. But despite the differences, they all share some common things, like traditional dances, music, and art.
This common culture is what we call the Indic cultural sphere. It is made up of all the cultures that have developed in the Indian subcontinent over thousands of years. And even though these cultures may have their own unique identities, they are also connected by their shared roots.
So, when we talk about the Indic cultural sphere, we are talking about all the different cultures, traditions, and ways of life that make up the diverse tapestry of India and its surrounding regions.
