It is our great Indian culture that is the only misterious and interesting thing which would more than enough to fill all the books in the world
India is a wondrful place having the following timeline- The Vedic Age [Prehistory to 600 B.C.]
The Age of Imperial Unity [600 B.C. to 320 A.D.]
The Classical Age [320-750 A.D.]
The Age of Imperial Kanauj [750-1000 A.D.]
The Struggle for Empire [1000-1300 A.D.]
The Delhi Sultanate [1300-1526]
The Mughul Empire [1526-1707]
The Maratha Supremacy [1707-1818]
British Paramountcy and Indian Renaissance, Part 1 [1818-1905]
Struggle for Freedom [1905-1947]
finally free India....
talking about our culture then i have to say we had the culture of respecting every elderly person.....moreover only in India we respect teachers so much that he is given the immediate place after our parents.......if u understand hindi....then understand this-"guru brahma, guru vishnu, guru devo maheswara, guru sakshath parabrahma, thasmy sri guruve namaha"..(if i'm not wrong)
so i can say it is impossible to for anyone to define India's true culture....
hope i helped u
