What I know about India:
Anything found in the novels of Vikram Seth, Ruth Prawer Jhabvala, Salman Rushdie.
Some of the provinces' food. YUMMY!
A bit of Hindu philosophy, especially about Brahman, Brahma, Vishnu and Kali. Hanuman, Ganesh and Krisna. Buddha.
The English were idiots, to build canals all over a tropical continent. It was a good thing you all helped Gandhi to politely ask them to leave.
