A fire – that is what a woman is, Gautama.
Her firewood is the vulva,
her smoke is the pubic hair,
her flame is the vagina,
when one penetrates her, that is her embers,
and her sparks are the climax.
In that very fire the gods offer semen,
and from that offering springs a man.
– Brihadaranyaka Upanishad 6.2.13, ~700 BCE, Transl: Patrick Olivelle
