PERFORMING AN ACTIVITY IN ITS ENTIRETY FROM START TO FINISH seems to refer also to the elements individually as「motions of person squatting and using mooned orifice between spread legs」while performing an activity in its entirety from start to finish with the motion of passing between walls,「evacuation of bowels」「motions with a bucket」and so on describes DEFECATING, an activity that can be agreed upon universally as one that should not be paused or stopped in midstream, for any reason…try to imagine that.「Motions with use of a receptacle or an open cavity to temporarily hold some contents, such as untreated excreta transported without water (e.g.,「shimogoe」via containers or buckets).」
　「Motion of passing through stiff walls」such as would be displayed by a female primate in estrus might be the PATH, the ROAD, the WAY of all primates and human beings and most other animals as well in order to assure the survival of the species…perhaps the answer to the question:「Why was I born?」(to eat, survive, and reproduce). Note that each person may have an individual MANNER OF DOING that task, but one way or another it must be done or we die out as a species.
　Alternatively, some sources try to claim this glyph depicts the「motion of using a shuttle」of a loom that passed the weft threads from one side to the other between the warp threads. The WAY OF DOING meaning perhaps stems from the fact that there were different weave designs, such as twill.
