Assuming that the translation is accurate here, then I certainly have no question Chas V’shalom on what the Rebbe says. I would just like to understand it better.

Also, where/how can one see these and other posts?

Now, in your translation of 20 MENACHEM AV, 5745 (1985), I have found a one:

“This is implied by the Rambam’s statement: “[Maintaining] the

body’s health and complete state is among the paths of the ser-
vice of G-d.” The Zohar declares12 “The strength of the body is

the weakness of the soul.” However, that does not imply any
contradiction to the above. Rather, when the emphasis on the

body’s strength comes from the body, it weakens the soul. How-
ever, if the emphasis on the body’s strength comes because of

the Torah’s command, it will surely strengthen the soul. On the
contrary, such an approach will weaken the material nature of
the body and make it a more complete vessel for the soul.”

Nice!

“This story is rather difficult to comprehend. After these events,
Rabbi Yosef Caro composed the Beis Yosef and the Shulchan
Aruch, two great Halachic works that have guided our people
for generations. If he would have died Al Kiddush Hashem, these
texts would never have been written. Thus, we are forced to say
that had he died Al Kiddush Hashem, he would have attained an
even higher spiritual rung.”

I don’t understand the logic here. On what basis must we conclude: “Thus, we are forced to say
that had he died Al Kiddush Hashem, he would have attained an
even higher spiritual rung.”? Perhaps in some sense he would have reached a higher “spiritual rung”, but didn’t he actually serve HaShem – so to speak – even better now that he “composed the Beis Yosef and the Shulchan
Aruch, two great Halachic works that have guided our people
for generations.”?
Am I missing something here?
