The tattoo can only exist as part of the skin, as a drawing always is an incision in the material and therefore cannot be parted from it. - Antoni Tàpies

Later came 'the hour of solitude'. Inside my tiny bedroom-studio, I began my forty days in the desert; I do not know if they are over yet. With a desperate, feverish rage I took formal experimentation to maniacal levels. Each canvas was a battlefield where wounds multiplied ad infinitum. And then came the surprise. All that frenetic movement, all that gesticulation, all that unending dynamism, by dint of the scratches, blows, scars, divisions and subdivisions .. ..suddenly took a qualitative leap. My eye no longer perceived differences. Everything congealed in a uniform mass. What had been ardent ebullition transformed itself into static silence. It was like a great lesson in humility for the pride of my unbridled quest.

Everything takes place in an infinitely greater field than what is framed by the size of the picture or by what is materially in the picture. This matter [door/window/wall] is but a support inviting the viewer to participate in the much larger game of a thousand and one visions and feelings; it is the talisman lifting or sinking walls into the deepest recesses of our spirit, opening and at times closing windows in the construction of our impotence, our bondage, or our freedom. The 'subject-matter' then may be found in the picture or it may exist solely inside the spectator's head.
