Scholars explain this element is depicting a young Chinese girl child's hairstyle that tied her hair up on each side of her head with one bun-like shape on each side, and that therefore this element came to mean YOUNG GIRL CHILD who perhaps was still a virgin, but certainly PREPUBESCENT, UNDERAGE with the additional meaning of DIVINE, or a divine experience. Suggestions are that the two tufts of hair were used as handles to maintain control over the young head while confronting head-to-head giving and receiving head in a divine experience, and while unconfirmed, this scenario is undeniably plausible…see 取「ear with crotch」meaning 'to take control' 'to butter up, curry favour' and 'an active partner.'
　Witch doctor shaman purveyors of religion, sex, and medical aftercare to infected clients offered young girls for sale or short-term rentals as a divine, heavenly experience…with satisfaction guaranteed. The association of this hairstyle with divinity was integrated into Japanese imagery when creating their male deities having the same hairstyle as prepubescent Chinese girls.
　Depicts a CRESTED HEAD, as in the feathery crest of birds, or any sort of head that is「raised and cresting」(requires little imagination). An additional modern usage is for MINERAL ORES, PRECIOUS ROCKS AND STONES that are「raised higher」from within, as the glyph also appears as might a hollow mine SHAFT, and refers to a gushing oil well, a GUSHER.
　As SHAFTS EMERGING, RODS RAISED it is often replaced or interchangeable with another element meaning「emerging shafts, flowering, plants (艹)」noting that a flower as it first opens is unpollenated, unfertilized, and is the plant equivalent of a virgin. An opened flower often contains raised shafts that are its sexual parts (pistil, stamen) which may account for the similarity.「Flower」is the euphemism for a virgin girl in a lord's harem, and was the source of the term「to deflower.」
　An older version was「crafty, closed orifice, flesh seam」with「watery, fluids, juicy」(汞), not unlike the proverbial juicy flesh seam of a 'freshwater clam.' Replacement is 礦, literally「spread, numerous」with「rocks, stones」that also refers to BUNCHES OF HAIR ON EACH SIDE OF A HEAD, but not likely a head located between the owner's shoulders…and「rocks with cave of yellow, pus」is further suggesting the rampant conditions of sexually transmitted disease that sent folks on to heaven, becoming divine (i.e., death) at a young age.
