The [consummate] revelation that “This is not a common place,” [that
within the Beis HaMikdash will be a fusion of finiteness and infinity,]
will be in the Third Beis HaMikdash. To explain the concept: The First
and Second Beis HaMikdash [reflect] the four letters of the name
Havayah (Y-H-V-H) which in turn allude to the Ten Sefiros. {The First
Beis HaMikdash represents the first hei (Binah) [of that
name] through which is revealed the yud (Chochmah). The Second
Beis HaMikdash represents the latter hei (Malchus) through
which is revealed the vav (Zaer Anpin)}.1
The Third Beis HaMikdash represents the level of Keser, as noted
above (sec. 3) that the “Lion will come” is the revelation of Keser that
transcends the chainlike progression of spiritual existence.
Within the Ten Sefiros, the aspects of revelation and concealment (oros
and kelim, lights and vessels) function as two distinct entities. [The
awareness that] both revelation and concealment are [merely] names of G-d who
transcends them both, is a result of the revelation of Keser that
transcends the chainlike progression of spiritual existence.
[To elaborate on this point:] The distinction of the Sefiros [as
separate entities] (Chochmah, Binah,...) is (primarily) relevant
with regard to the revealed Sefiros of the realm of Atzilus. With
regard to the Ten Concealed Sefiros2 of Keser, by contrast,
all these different levels are united as one. Similarly, with regard to
the distinction between the oros and the kelim (revelation and
concealment), within the Ten Concealed Sefiros, they (the oros and
kelim) are united.
Based on these concepts, it can be explained that the consummate revelation
that ‘This is not a common place” will be in the Third Beis HaMikdash.
[There it will be manifest] how space itself will serve as a receptacle for the
revelation of that which is above space. For then it will be revealed within the
names Havayah and E-lohim as they function within the chainlike
progression of spiritual existence {and as a result, also in the two dimensions
of transcendence and space, even as they exist within this physical world}, that
they are both [merely] names of G-d, who transcends them both, [and thus they]
are truly one.
The above also enables us to understand the frequently made statement (cited
above sec. 1), that the unique dimension of the Third Beis HaMikdash will
be its eternality. On the surface, since the First Beis HaMikdash as well
could have been eternal (as mentioned above ch. 3), why do we say that this is
the unique dimension of the Third Beis HaMikdash?
It is possible to resolve the question as follows: The perpetuity that could
have been manifest in the First Beis HaMikdash would have resulted
(primarily) from the revelation of [the dimension of G-dliness] that transcends
time. The novel aspect of the Third Beis HaMikdash lies in the fact that,
[in the Era of Redemption,] time itself will serve as a fit receptacle for this
level,3 [i.e., that the dimension of timelessness will be
revealed, not in contrast to the nature of the world, but in a manner that will
permeate the nature of the world itself].
This is why the unique dimension of the Third Beis HaMikdash will be
its eternality. For the true dimension of infinity (eternality) is that the
eternality does not come solely as a result of influence from above, but that
the lower level itself serves as a fit vessel for this. Eternality of this
nature will be manifest only in the Third Beis HaMikdash.
