India is known for its cultural diversity and it is marvelously visualized in the basic form of festivals, languages, and traditions in the states and regions.
Festivals
India celebrates numerous festivals which can be seen as the unification of religious and cultural differences, such as “Diwali”, a festival of lights that could be celebrated everywhere, but varies regionally. Contrariwise, Durga Puja is the most spectacular occasion in West Bengal, the Kerala harvest festival gets its expression from Onam, whereas Lohri is celebrated in Punjab and Bihu in Assam, indicating the agrarian way of life of these areas. Immense religious diversity in India can be linked to Eid, Christmas, and Guru Nanak Jayanti.

Languages
India has 22 official languages and hundreds of other dialects, which is a clear example of the linguistic differences. For example, Hindi is the most spoken language in the northern states while the southern states have lots of languages like Tamil, Telugu, Kannada, and Malayalam. Moreover, the other languages like Bengali, Gujarati, Marathi, and Punjabi also feed this linguistic diversity. Traditions
Traditional clothes, food, and art have diverged greatly in problems of one region after another. Rajasthan traditional dress is ghagar-choli, Punjab traditional dress is phulkari embroidery, and Assam traditional dress (mehkela chador) is some of the regional wear. The food tastes and traditions which are so diverse can be seen, for example, from the spicy Rajasthani curries to coconut-rich Kerala dishes. Kathakali is a ballet dance from Kerala and Odissi is a dance form of Odisha and both are preserving their ancient origins.
