Greetings and blessings,

[I received your] letter with a note concerning what is written in Kuntreis Chag HaShavuos, 5711, [Sefer HaMaamarim 5711,] p. 278: Der Kohen Gadol, macht der Rebbe; “[The Divine service of] the Kohen Gadol, the Rebbe achieves.” In my notes to the text, I stated that the intent there is somewhat [unclear and] requires analysis. You sought to explain the matter based on what is stated in Avodas Yisrael (by the Maggid of Koznitz) in the discourse regarding Yom Kippur, that tzaddikim elevate the Kohen Gadol and the sheliach tzibbur.1

This does not appear to me to be the intent, because at present, there is no Kohen Gadol,and if his intent was the sheliach tzibbur, the fundamental point is not present in the text, [for no mention is made of him]. In my opinion, the intent is that the Rebbe Rashab explained the spiritual counterparts to all [the dimensions of] the service of the Beis HaMikdash in the individual Divine service that a person must bring about within his soul. When he reached [the service of] the Kohen Gadol, he said: to reach something comparable to the spiritual service of the Kohen Gadol, this is accomplished by the Rebbe. Once that is accomplished, a person who is motivated can carry out the spiritual equivalent of the service of the Kohen Gadol.

If this is the intent, there are two seemingly contradictory new concepts brought out by this teaching:

a) that everyone is obligated to carry out the service of the Kohen Gadol; as obvious, this refers to its spiritual counterpart. (See Tanya, Iggeres HaKodesh, Epistle 29, [which states that every person will reincarnate until he fulfills all the mitzvos,] “except the mitzvos concerning a king,” without making a similar exception regarding the mitzvos that concern a Kohen Gadol. See Shaar HaGilgulim, Hakdamah 11 and 16; Shaloh, the beginning of Chelek Torah Shebichsav, the introduction to Toldos Yaakov Yosef).

b) That it is impossible for him to begin this service until, at the outset, he is given assistance in becoming a Kohen Gadol.

Further analysis is still required.

With blessings for your recovery in the near future,
