This set of window paintings is a return to a technique/theme with which I was 20 years ago. In those days, the window assembledges were 'purely' windows and led to a formal/minimal statement as squares, rectangles, and stripes. I rejected any symbolic (female) implication.
"one-in herself' refers to 'virgin.' In the old/true sense of the word, virginity was NOT a physical condition but, rather, a spiritual understanding woman (and, even, society) had of herself. She was her own person.
