Superb piece!
One might also say that within OCD, it is uncertainty and doubt that replays in the mind and ultimately the ego cannot break this pattern because it depends at times on the doubting/fear when we don’t want something or trouble and to reject/avoid them, we give in too much on one side.
Overall it is like a snake who eats himself (Ouroboros) because the snake believes that to live and exist, it must eat itself and nothing else in order to avoid being nonexistent. But on the contrary it if it eats itself all then it SHALL become gone, all so that the best and right (whichever it may be to the doubter) decision can be made.
OCD is like that IMO. Balance is key but to some it’s confusing to know what is the “real” value of each side in order to be balanced. If we want perfection and we overdo it then when is the time to stop and how? That’s the ultimate question can be found within mediation.
