What I've enjoyed most though is meeting people who have a real interest in food and sharing ideas with them. Good food is a global thing and I find that there is always something new and amazing to learn - I love it!
India is the meeting place of the religions and among these Hinduism alone is by itself a vast and complex thing not so much a religion as a great diversified and yet subtly unified mass of spiritual thought realization and aspiration.
Always give a word or sign of salute when meeting or passing a friend or even a stranger if in a lonely place.
