My first experience of that was with my first movie which I did in India. And it was so different from other people. I find that "Oh my God." Every time the music is slow I feel that people are going to get up and go out. You get this nervousness. But, to my surprise, people starting singing the song even before it came in. They started singing along a week later, after release, which was very cool.

We didn't want to do that. It would have been a beautiful moment in the movie but it would have brought the movie down. So Danny's vision was perfect I think when he wanted it to be driven at the same time having this new emotion about this boy coming as a hallucination or like a déjà vu and as the future kid.

Music is language itself. It should not have any barriers of caste, creed, language or anything. Music is one, only cultures are different. Music is the language of languages. It is the ultimate mother of languages.

Each one of us has our own evolution of life, and each one of us goes through different tests which are unique and challenging. But certain things are common. And we do learn things from each other's experience. On a spiritual journey, we all have the same destination.

How we approached this was I wanted this to be personal in a way. It's not a big, epic Hollywood score but really personal and intimate, and we thought guitar would be the perfect instrument for him because he's young and he has an undying spirit and all that stuff and we went on that feeling totally.

All my life I have had a choice of hate and love. I chose love and I am here

Because when you work with a different team, the expectations are different and then you deliver in a very different way. You look back at it and you're proud of yourself. And when the same people come in and you do the same thing, it's boring. You could re-envision it again and again but when the new chemistry of ideas comes in, something happens as a team.
