FEELING CLEARED AND BALMY, and significantly, 'balm' is any of various slippery, strong-smelling, and/or resinous substances often of medicinal value exuding from certain woods and plant shafts, especially those from hot and wet, humid, steamy regions.「Tonguing female」or euphemistically a「singing girl」both frankly are a girl with a dexterous tongue. A DIVA today is a highly distinguished female singer, and the word originates from「divine, a goddess, a really good singing girl」who was trained as the apprentice of a divining female, the local shaman witch doctor…「singing girl」is a euphemism for a superb sexual services provider, perhaps since she can use her tongue so well or because she causes her clientele to cry out loud and burst into hollering song.
　Shamans sold the services of these girls, and sold the girls themselves, too…called 'witch doctors' because they also sold divination religious services along with sex, and attempted to doctor you up after you contracted a sexually transmitted infectious disease.
　「Viewing women as commodities [see 品] was also made customary from Song Dynasty (960 - 1279) forward, both in the suddenly expanded labor market and within relationships. Men could sell their female kin to slavery or prostitution, and frequently did.」

　Some scholars say these elements are「sun with female」who is with you picnicking at ease on a clear day, spending time with you only when you need her during a short-term rental period as an escort, and to clear one's piping with her blowing windpipe, so necessary for clear tones while singing.
