「Able to distinguish and recognize the difference」between clean emissions and those with gonorrhea.「Repeated bobbing head with sticky splats, wad」with「keeping watch, space between thumb and middle finger (about the size of an anal poultice?), taut buttocks」as TO RELEASE, and has the same pronunciation as the word「Buddha」in Sanskrit, or so they say. Together meaning to「distinguish and recognize Buddha as ___」[you can fill in the blank here, noting that the sages were themselves Taoists, which may account for so many derogatory references in glyphs to Buddhism].
Otherwise meaning to INTERPRET and EXPLAIN, to ELUCIDATE. The English word 'elucidate' literally means to cause something to become clear, lucid and shining, glossy as does a wet surface reflects light.
The sages lampooned religion in glyphs as often as they lampooned royalty, but more often than they lampooned most everything else. Formerly depicted a line of prisoners or slaves chained together by tying everyone's penis and scrotum above the testicles at very short intervals (about one foot apart) to prevent escape by causing the group to move in unison or risk falling over and preventing them from running off, but the close proximity to the person in front of each prisoner, combined with the various deprivations normally associated with captivity and the restricted outflow of blood from the genitals may have promoted some repeated anal bobbing actions of each man in line with the person in front, even if accidental and not a deliberate attempt at penetration. These physical conditions to which the prisoners were subjected EXPLAINED all these various and obvious actions, likely thought as quite comical by the guards. Note that the sages generally were not adherents of Buddhism, so to disrespect that philosophy caused no concern among them. Further note that it was unlikely slaves or prisoners would have ever been given「rice repeatedly」to sort out the pebbles as some scholars suggest, nor be given rice for any other reason, either.
