Yves Klein quote about freedom and bars

Pure, existential space was regularly winking at me, each time in a more impressive manner, and this sensation of total freedom attracted me so powerfully that I painted some monochrome surfaces just to 'see,' to 'see' with my own eyes what existential sensibility granted me: absolute freedom!

I am against the line and all its consequences: contours, forms, composition. All paintings of whatever sort, figurative or abstract, seem to me like prison windows in which the lines, precisely are the bars.
