Our thoughts determine our age.

I see so many activists... who are artists because they feel that they have the power of communication.

I always believed that my work should be unfinished in the sense that I encourage people to add their creativity to it, either conceptually or physically. Back in the 1960s, I was calling for 'Unfinished Music,' number one, and number two, with my artwork - I was taking unfinished work into the gallery. And that's how I was looking at it.

We are all dreamers creating the next world, the next beautiful world for ourselves and for our children.

I relate to happiness as an ecstatic moment - something you don't create, you encounter.

When you are suffering, you become more understanding about yourself, but also about other people's sufferings too. That's the first step to understand somebody is to understand their sufferings. So then love follows.

When you are feeling bad, do one thing a day to make your heart dance. It could be a simple thing like looking up at the sky.
