Hi Horace,
There is a lovely book called Spiritual Tarot by Signe Nchols, Robert Mueller, and Sandra Thomson.
It is illustrated with the RWS, Aquarian and the Morgan Greer.
Here is their take on the woman in the Judgement card.
I thought it was very good.
In the Morgan-Greer card, the figures of a man, woman, and child face us, the man and child extend their arms upward and outward.
Dark blue, these figures exemplify the release that arises when we respond to the call (trumpet) to face our shadow aspects, using the inspiration or purifying flames of divine energy.
The flames emanate from spiral-like clouds, suggesting that our awareness will be cyclic.
Our feminine, or inner mother, aspect will protect us in our work, signified by the female with her hands protectively over her breasts.
My thoughts;
The way her hands are held high on her body reminds me of the way you hold a baby.
Even the tilt of her head is what you do to rest your cheek against your babies little head and it gives them more support and sense of security.
So I see her as protective....and comforting.
