Item: I own a 'Solomon's dagger', actually a short sword, with a hexagram on the hilt. It is very nicely made. It is unsharpened of course, although the tip is a little pointy.
The Hexagram also represents union between the feminine and passive yin force(upside down black triangle) and the masculine and active yang force(right side up white triangle).
Which also means as a reunion of all polarities, and as such, a symbol of balance.
It has many many purposes, and is one of the best symbols in the occult.
I don't know too many "passive" women. We all of some of the inherent traits of our opposite. You will recall that the Yin/Yang symbol shows a bit of yin in the yang and a bit of yang in the yin. If you consider that the yin energy comes from the earth, a rising up as in plant growth, it takes a lot of strength to make that happen.
And yes, all things have both yin and yang to them. THe Earth itself is not receiving its powers from an external force, and is acting(not reacting or transmitting) even though it is feminine. The Earth is a creator, and a mother, in the aspect you point out, of giving us nourishment and life, sheltering us, though the Earth is also cthonic, deathly. For flesh rots away, and returns to feed the Earth. Both light, and dark aspects to the Earth, as well as masculine and feminine.
You can evoke female aspects in me, even though I am male. Light can burn and kill and destroy, darkness can act as the womb of genesis, much like female warriors and magi(the Magus, from Tarot, both roles assuming direct action) thrive, just like male priests and oracles(who assume a role of receiving and acting as channels).
Lilith is far from submissive, though she can be receptive. Just look at her lunar associations. The moon shines sunlight, it is a receiver and a transmitter of sunlight, in its own form, which is moonlight.
Wait, I should also add that there are men, who have and can act as excellent mother figures, and women who have and can act as father figures. Neither gender nor sex can or should be a limitation in magical practice, a hoop to jump through.
While I cannot detail the working, I know I have performed magic that would ordinarily have been performed by a woman. And many of the most powerful spirits I have met, are indeed female; one of which is a queen, a warlord(warlady?), and a magus.
Yes, there are places where gender and/or sex matter, but they are not meant to be limitations.
