The reason why we are taught to perform ordinances with exactness is not for brain washing.A big reason is so it is easier for patrons to feel the spirit. I will give an example without going into specifics. There are two ordinance works, worker "X" and worker "Y". If worker " X" were to perform ordinance "A" different then worker "Y" then the patron would pay attention to way worker "X" performs ordinance "A" and would lose focus on the spirit that prevails in the temple. Also this why correcting patrons when they are performing ordinances is usually frowned upon ( or at least should be) A good rule I used is correct once, and if they do it wrong again simply move on. OP it sounds like were eluding to being corrected multiple times. were you corrected a lot during your endowment?
