Sholom Aleichem, Zev7. Welcome to the CR.
Interesting point. I think you are saying that a person does something not because of any personal motivation, and certainly not for his own gratification, but simply for the sake of it. You described it almost as ‘instinctively’.
Whether such a Madreiga exists I can’t tell you. But that shouldn’t be pshat in the Rambam “????? ???? ???”; according to the way you understand it isn’t a conscious logical decision to do something; it is an instinctive action. Is that called ????? ?????? Is that what HKB”H wants from us? I could understand that HKBH would want us to acheive such a Madreiga that this is possible, but I don’t think the ideal performance of a Mitzvah should be something other than a positive decision to do this albeit all other considerations.
I have heard an interesting Pshat in the Akeida – it says ????? ????? ?? ???. The Meforshim talk about why we need to know this. Obviously taking something involved stretching to do it. I once heard (don’t remember mekor) that Avraham Avinu was on a level that his body instinctively did the ???? ?. He had no Torah, no form of knowledge of the commandments, but his absolute purity allowed his body to be on a level of complete holiness, and his body would automatically do what was desired by HKBH. However, taking the knife wasn’t ???? ?; HKBH only told him ?????? ?? ?????. HKBH ultimately didn’t want the knife. Therefore he required the extra effort ????? ???.
