Gateless gates is one of those paradoxes used in the teachings of Zen in order to help the students realize the nature of things.  It is not about a gate, but about the mind being transformed by confronting the paradox.  For me, making art is also a transformative confrontation.  It leads me to experience no gate or barrier, the work and I become one, there is no more inside and outside.  My process of working -layer upon layer of lines, marks, paint, glass or stones - seems to conceal what is not and reveal what is, what I call 'essence.'  To apprehend this essence, which is beyond thought and has no boundaries, the viewer too needs to go through a gateless gate.
