Sting

Sting has always been totally open about his ayahuasca use and the spiritual and musical enlightenment he has gained from the brew.

In his book 'Broken Music', he recalled on particular experience with ayahuasca that had a profound impact on him.

He wrote: "I may be out of my gourd, but I seem to be perceiving the world on a molecular level, where the normal barriers that separate 'me' from everything else have been removed, as if every leaf, every blade of grass, every nodding flower is reaching out, every insect calling to me, every star in the clear sky sending a direct beam of light to the top of my head.

"This sensation of connectedness is overwhelming. It's like floating in a buoyant limitless ocean of feeling that I can't really begin to describe unless I evoke the word 'love'."
