HEMP fibers are capable of making strong and soft textiles, such as would be used as a medical dressing and「cloth for one's sack」: SACKCLOTH needed after taking home a SOUVENIR GIFT from the shaman's「meat pile for emerging shafts」brothel in the form a sexually transmitted infection.
Elements initially suggest FEMALE human beings as「sacks of meat, bound with strong cloths」around their no-longer-integrated feet, and also used for other purposes depicted in roles as「blow job providers, meat pile.」
Female hemp plants produce far more of the psychoactive material for which the plant is desired (for some uses) than the male plants, ostensibly to protect the developing seeds from the hottest of the Sun's heat with the most resin proportionally contained within the seed BRACTS that surround each seed in a small WRAPPER. Consequently, most cannabis cultivators keep only a limited number of male plants alive in order to pollenate the females and produce some seeds for next year and for culinary purposes, but also to prevent many of the female plants from morphing into males, as they will do naturally when no male plant shafts are nearby, to attempt fertilization of one another (not unlike conditions in a large harem). Nearly all of the harvested hemp stalks used for burlap, or any other uses, are female plants.
FEMALE HEMP PLANTS remain so「only on a temporary basis」in the presence of no males. Now, it is tempting to draw a parallel here with the Chinese emperor's vast harem of literally thousands of concubines to describe what happens naturally among a harvest of beautiful human females bunched together when no male is nearby for long periods, as「emerging shafts in meat piles, oral pleasure」with one here and another one there turning upon the others nearby for giving and receiving satisfaction. Perhaps a reference to digital penetration with simultaneous cunnilingus, something akin to being finger lickin' good, as they say.
