Ultimately shiva and shakti are one. What we experience and everything else are layers so to speak… the tantras call them tatvas - from complete awareness down to earth.
I don’t think there’s a tatva for gender @Maoshan_Wanderer would probably have a deeper understanding here? But extending the concept out and experiential understanding, everything is him/her and male and female bodies is an expression of this, a type of layer of awareness we experience
I know about he tattvas too. They are the vibrations of the elements. Vayu, Tejas, Apas, Prithvi- Air, Fire, Water, Earth.
But first of all the primordial Father-Mother technically are Prana (Father/Masculine) and Akasha (Mother/Feminine) substance wise.
You’re looking for which ones are masculine and what’s feminine? I mean a lot of the time Fire (solar) is considered masculine and water (lunar) feminine…Air is more masculine too because it’s characteristic movement and mobility, Prithvi or Earth is the crucible where they all meet- it’s receptive, so is considered more feminine.
Idk if it’s really that cut and dry because Shakti/Kundalini is a feminine Fire. Technically Kundalini is the condensed Akasha within us at the base of our spine.
But yes Shiva and Shakti are one. Everything is one within the Absolute/Source and gradually becomes separate as matter, energy, and consciousness further unfold and complicate into manifestation.
EVERYTHING that exists is different modalities/aspects and densities of the primordial Father-Mother (Prana and Akasha).
What differentiates all different forms of matter from each other?
-THE MORPHIC FIELDS
The Morphic fields are what make a leg a leg, and arm an arm, a tree a tree, a mineral a mineral, etc etc.
Awesome response. Just to expand, the tatvvas also include all the layers of reality, from oneness down - karma, the mind, elimination etc
Thinking about it… the masculine & feminine don’t fit here really as they are equal, as opposed to one layer being “higher” than another.
I feel though, that male / female bodies are maybe just a beautiful expression of duality 
Oh yeah for sure. We can even take advantage of the tattvas for success in life. Like performing certain tasks, business ventures, etc during when one tattva is most prominent at the time. We can talk for a while about this stuff.
Let me just conclude with this:
Woman is the most beautiful divine creation of the Light :)
Nice perspective, and agreed. She is
