Being a woman at least in the "collective subconscious" is referring to a human being which "gets", "receives".
The body of the woman physically receives the man, this "hollow" has other implications like receptive,
acceptance, expansion, and also some "negative" downsides: exploitation (an angry woman during divorce...),
backstabbing (because she is not "direct").
A woman is a modality of being, you can be masculine so you develop the "hero" archetype, the soldier, the
bread winner, the competition, the brotherhood of men.
But you cannot fake those internal modalities. If your mind is "yin" you are a woman, period, even if your body
is not congruent. The hardest part is to know really if you are living at your highest potential or not.
