Elements are apparently「flows and rising」or「fluid with morning meat.」Tides are caused for the most part by the Earth's rotation and the gravitational attraction between the Earth, Moon and Sun, generally occurring twice each day. Seawater both rises and falls due to tides, and at ebb TIDE is the best OPPORTUNITY for birds to feed on clam meat, for example, and the incoming tide carries with it all sorts of possible treasures from the sea. Tidal currents provide opportunities for quicker travel by ship. Tides also travel up and down rivers for some distances, and, cause anchored boats to rise (and fall) relative to the tether. If the water level drops, there is not usually a problem…but if a boat is tied tightly to a dock with a short line without considering a later rising tide, the boat may be swamped and sink. Elements as「flow from imbeciles in the morning」relates to the ubiquitous male human morning erection, and you can imagine yourself how all these meanings might apply. Some sources suggest these elements are water with rising sun and moon yet tides occur worldwide regardless of whether these celestial bodies have risen locally.
　Feces are generally fairly SALTY:「fluid flow with imbecile's meat」as some sort of OPPORTUNITY. May be referring to a careless service provider who did not fully remove all grains of salt from her feet, or, to the client of course: concubines and service providers used salts in the deep skin slits of their bound feet to accomplish two things at once: dry the skin, and disinfect any wounds or straggling bacteria left by clients: SALTS were rubbed into the flesh seam created by bending over the sole of each foot into a hairpin shape, and it requires little if any imagination to understand how this condition also applies to all the given meanings. A likely source of the English expression meaning to accept the bad along with the good but have some skepticism and reservations,「take it with a grain of salt」and seize the OPPORTUNITY anyway. Even only one single grain of salt remaining in the flesh seam of a no-longer-integrated foot would cause discomfort to a client.
