In times gone by, most every newlywed female soon learned the obvious, hard truth of the matter, that is, a male's FEELINGS, THOUGHTS, INTENTIONS, MIND, HEART, SOUL and INTELLIGENT PLANNING were all centered around one thing, and it was not her. The ancient Chinese sages who created these glyphs were at the very least forthright and frank, if not politically correct by modern standards, about this and most all other matters. Today? Who knows…?
　There is an old Western apothegm that suggests "the way to a man's heart is through his stomach." Disregarding the incorrectness of the anatomical references, the Chinese sages knew better, and described so using this glyph.「Penis with drops flying」all around, as the true way to the male heart and soul, is generally applicable to males of nearly all species possessing adequate blood levels of testosterone, imbued by DNA with the behavioral code of: …eat…survive…reproduce, …eat…survive…reproduce [ad infinitum] in order to insure the continuation of the species. Translated into English vernacular, …eat…survive…reproduce is simply: food, fight, fuck. Now, who can argue that this encoded DNA is not at the heart and soul, generally, of the class of animals known as human males?
　Glyph is obviously a depiction of something in distress and/or a dangerous condition, such as a smelly bodily organ or a baited hook with a few surrounding flies: spewing flying drops of pus from one's curled and twisted penis…see 疒, a「bent erection with fluid flows.」Not coincidentally, eerily similar to 灬. Possibly only the epitome of self-delusion make-believe in all things as pleasantly benign will conclude these strokes depict anything that resembles a healthy happy human heart.
　Most doctors, medical students, or nurses with basic knowledge of anatomy will confirm that the symbol used for a heart in the West (❤) does not resemble the shape of an actual, physical heart functioning as a bodily organ for pumping blood (see 蕊). So, that raises the question: what did the shape formerly depict when that symbol was created? clearly not an actual heart, but instead what thoughts were in a person's heart and mind, or if it must be something tangible, perhaps the visible area around where a heart might be found. Any four-year-old child can tell you what the shape of the heart symbol resembles most on the human body: full mammary glands of the bosom where the heart is located, or, other rounded, fleshy areas of the body with some sort of cleavage in the center, such as buttocks visible while in the lordosis position (the Western heart shape formerly was drawn with a small loop extending down between the humps to depict the anus). That is to say, the symbol refers to what was in the heart and mind of most early human folk—not always of course, but more often than most anything else after an animal is fed sufficiently. Same is true for this glyph as what is「heartfelt」in 發 and 発 divulging true feelings of the heart, the human soul as it were, the seat of intelligent planning, one's nature, characteristics, essence, one's true heart (性).
　Nevertheless, a medical fact that likely was known by clever Chinese sages who had no religious qualms about conducting autopsies to learn more about illness is that, if left untreated, gonorrhea causes the deterioration of heart valves, with leaking and「spewing drops」as it were. Untreated syphilis also causes neurological and severe cardiac symptoms.
　Interestingly, both「heart」and「soul」are represented by the same imagery (see 魂「demonic cloud」and 荇「shafting performance」for details). Ask yourself why「listening to your heart」(恥) is a dishonorable shame and disgrace, an「understanding heart」(忿) is filled with exasperated furious hatred and indignant rage,「flow from [this organ]」(沁) means saturated with infection, and「sheep schtupping (ejaculation into a birth canal or other attainable orifice)」(恙) refers to syphilis …the reason is not due to asserting one's individuality or individualism as some teach.
　This glyph (心) as formerly drawn long ago resembled an adult scorpion with two pincers, body and tail, but what strokes remain today seem to be only a barbed appendage pumping drops of venom. The oldest Chinese for this glyph also clearly resembled, in detail, an adult human penis with scrotum and testicles on each side, including the meatus …(try an Internet search to see for yourself).
　Human HEART, MIND and FEELINGS, -HEARTED or -MINDEDNESS, the SOUL and seat of INTELLIGENT PLANNING. Scorpion venom from a telson, a human heart, and the male penis literally or figuratively are all referents associated with pumping fluids, regular beating, some hard pounding at times, deep penetration and throbbing among other analogies in most every language on the planet. Note that the Chinese greatly respected scorpions (not a bad idea) and equated scorpions to human beings in many ways, so that this representation of INTENT, HEART and MIND is not necessarily all bad, just be careful of those THOUGHTS WITHIN ONE'S HEART and the mind or intentions of others—not everyone is benign, in fact.
