/**

I feel as though I have lived many lives, experienced the heights and depths of each and like the waves of the ocean, never known rest. Throughout the years, I looked always for the unusual, for the wonderful, for the mysteries at the heart of life.
I’m for mystery, not interpretive answers...The answer is never the answer. What’s really interesting is the mystery. 
If you seek the mystery instead of the answer, you’ll always be seeking. 
I’ve never seen anybody really find the answer, but they think they have. So they stop thinking. But the job is to seek mystery, evoke mystery, plant a garden in which strange plants grow and mysteries bloom.
