「Listening to one's heart」ought not be shameful except for a psychopath (for whom it never is), so these elements must convey a meaning other than what is commonly described by other sources.「Getting an unwanted earful」is one possibility, as when a service provider might turn his or her head rather than face the issue, perhaps considered a SHAMEFUL manner of doing business in the old days of shamanist teachings, or being a bit SHY at least.
　Glyph commonly believed to be「heart」is a scorpion's tail with drops of venom flying, or a penis and drops of jism schmutz or gonorrheal gleet or the pox as involuntary discharges, and as such, yourself and/or others「hearing that you've got a dose of the clap」ought to make you a bit SHY at least…but note that SHAME was attached to those feelings only after folks got a case of religion along with the clap (not all bad if it prevented the spread of disease, mind you).
　「Listening to a mind, spirit, intention like that of an appendage spewing venom」may be referring to someone who has acted upon some evil dream, idea, thought or desire and now is ASHAMED of doing so (yet once again, this scenario unlikely).
　「Soldier listening in battle, with a mind, heart, intent to adjust his position, change balance from one side to the other」acting SHAMEFULLY, DISGRACEFULLY, or DISHONORABLY after hearing a rumor or because his lord is obviously losing.「Listen, ear」resembles the shape of a vertical flag attached to a pole used in China and Japan to identify soldiers who must listen to commands or die, with flags marking who belonged to one side or the other of a battle. With「mind, feelings, spirit」means the DISHONOR, DISGRACE of a「soldier's feelings」deep in his mind of not wanting to die just yet, the true feeling in the minds of many foot soldiers in any battle prior to an attack, of not wanting to be hacked up into chunks or taken prisoner, tortured, anally abused, or forced to become some sort of slave.
　Refers to SHYNESS and「not wanting your feelings to be heard」(i.e., talked about) by others.「Soldier with his weaponry compartment and many drops」as「wet or wetted weapons magazine or storage area」a SHAME for a soldier, such as being so afraid that one involuntarily defecates or urinates, shits diarrhea in one's loincloth, or both. The reason for a feeling of「not wanting anyone else to hear」being the desire to hide something SHAMEFUL, DISGRACEFUL, or DISHONORABLE, such as fear prior to or during a battle, wetting one's weaponry and weapons storage area:「This process is so intense that soldiers very often suffer stress diarrhea due to redirecting of energies from nonessential parasympathetic processes, and it is not at all uncommon to lose control of urination and defecation as the body literally 'blows its ballast' and redirects all available energy in an attempt to provide the resources required to ensure survival. This is reflected in World War II surveys in which a quarter of combat veterans admitted that they urinated in their pants in combat, and a quarter admitted that they defecated in their pants in combat.」
