Flowers construct the most charming geometries: circles like the sun, ovals, cones, curlicues and a variety of triangular eccentricities, which when viewed with the eye of a magnifying glass seem a Lilliputian frieze of psychedelic silhouettes.

If I indulge myself and surrender to memory, I can still feel the knot of excitement that gripped me as I turned the corner into Rue Mimosas, looking for the house of Rene Magritte. It was August, 1965. I was 33 years old and about to meet the man whose profound and witty surrealist paintings had contradicted my assumptions about photography.

The question of truth is forever in the air, and people look for it with particular fervor in art.

Usually when painters use photographs, they enlarge and copy them and simply make a large, boring painting of a large, boring photograph.

And in not learning the rules, I was free. I always say, you're either defined by the medium or you redefine the medium in terms of your needs.

Then all at once in late August's heat, tall leafless stalks crowned with iridescent pink and purple blossoms burst from the purgatory in the earth. This arcane act of nature, though perceived by us as ordinary, is a manifestation of Maya's phantom play, the great immensity expressed in every way. My garden is the universe. I am the universe. I am my garden. All things are the same.

I believe in the invisible. I do not believe in the definitive reality of things around us. For me, reality is the intuition and the imagination and the quiet voice inside my head that says: isn't that extraordinary? The things in our lives are the shadows of reality, just as we ourselves are shadows.
