Cs, i do not believe that such an Arizal exists, because if it did, it would have been discussed here at some point, or one of the dozens of Lubavitchers who I’ve debated with would have told me, or i would have seen it in the messianic literature.
But I know very few maamarim of the Arizal, so please let me know if you find something like that, and we’ll discuss it.
I do appreciate your tone though; it’s refreshing.
As for Moshe and the soton’s image…no one thought Moshe rabbeinu was moshiach ben dovid, the final redeemer.
The nisayon of seeing Moshe dying wasn’t a yatzer hora of “let’s see if the jews believe Moshe died,” because what if he did? People die. Tzadikim die too.
The nisayon was what they did with that information. They reacted by saying not that Hashem will appoint another leader, and that they trust Him, which would have been fine… they said that Moshe had independent power, and they are lost without him. They have no way of reaching Hashem without him, so they chose something to be the go-between that they never needed…the egel was something that they saw on the kisei hakavod, and they gave it the same independent importance and holiness that they mistakenly gave Moshe.
Did Aharon know that Moshe was alive? Maybe. Maybe not. That wasn’t the point.
