The cumulative amount of man-made global pollution that's in the atmosphere now traps as much extra heat energy every day as would be released by 400,000 Hiroshima-class atomic bombs exploding every day. It's a big planet, but that's an awful lot of energy.

Unless we act boldly and quickly to deal with the underlying causes of global warming, our world will undergo a string of terrible catastrophes.

Every time you play you have energy within you - universal energy. That's the energy that keeps everything together - the planets, the galaxies. Everything.

Without movement there is no Life...We should use our energy to the fullest.

Our Pakistan elites are spoiled by permanent foreign aid and therefore find it difficult to change course. Pakistan needs someone who stands up and says: Fundamentalism is bad, capitalism is good. This region harbors enormous potential. Pakistan could become the hub for the energy that is transported from Central Asia to South Asia. That could change the whole region.

There is a spirit, an energy, that works with us. We've all felt it at some point in our lives.

As for super-stardom, I can say that I'm ready for anything. I feel like I've mastered so many stages in my life and the cool thing is, I don't see that energy changing anything.

Once in a while it vanishes - in the sense that I become deaf to beauty for a week or two or three. This coming and going of the inner life - because this is what it is - is a curse and a blessing. I don't need to explain why it's a curse. A blessing because it brings about a movement, an energy which, when it peaks, creates a poem. Or a moment of happiness.

In absolute terms, we may have to look at restricting the number of flights people take.

What I love about doing my concerts is always feeding off the fans and their energy.
