The aftermath of a good rainfall is a sight to behold, especial in the not-so-urban parts of India.
Speak of nature, and India really does have everything it all - valleys, mountains, beaches, forests, deserts and even a volcano that came back from the dead earlier this year! (It is on an uninhabited island on the Andaman & Nicobar islands though, so not very easy to get to!)
Beyond all, India is a profound experience. It is a learning of your own deeper self, and the values that you stand for. A typical holiday destination it certainly is not!
