The entire parshah are the WORDS of Moshe Rabinu in muusar or chizuk. There is only one ACT that take place in the parsha - Moshe designates 3 of the later-to-be six arei miklat.
A big part of the nechama is the fact that Hashem is here with us in galus & did nit forsake us to be on our own.
Where is Hashem? - Well, from the first line in Shulchan Aruch we see that Hashem can & should be right in front of you at all times! Shivisi Hashem l'negdi tamid - it is up to the person to bring Hashem to be in right in front of him always!
The biur halacha explains how one can have Hashem before him ALWAYS. Through the Six Constant Mitzvos. This is how we create a place for Hashem to be here right with us 'ein l'Hakadosh Baruch Hu ela daled amos shel halachah'. Not every place is available for Torah but the 6 constants create the opportunity for a constant presence of shechinah anywhere anytime.
It is interesting to note that at least 5 if not all of the six are in this parshah. [Shema contains 4. 'Es Hashem elokecha tira' is the 5th & even lo sasuru the sefe HaChinuch explains to mean not to follow desire without any constructive purpose & he says the same is included in the positive form in the mitzvah of ahavas Hashem.]
The chinuch draws a similarity to these six by using the Six arei miklat as the mnemonic device for the Six mitvos temidios. This represents the safe assylum of holiness that these six mitzvos create in our galus similar to the cities' protective assylum for a rotzeach in galus.
I'd like to extend the similarity to another point.
On the pasuk of v'ahavta es Hashem, Rashi says DO what He says out of love. Why does Rashi here speak about doing mitzvos out of love & fear, if we know the mitzvah is to love Hashem in our hearts, independant of other mitzvos?
I would like to say that just as the 3 arei miklat of eiver l'Yarden would not be effective until all of the six are designated, so too, the first 3 of the six constant mitzvos which are quite theological are actually dependant upon the other threes practical fulfillment. One cannot say he trully fulfilled the belief of Hashem Echad, if it remains just in the heart without practical fruition in action & deed. Here Rashi explains the mitzvah of ahavah & yirah on a practical level.
Nachamu Nachamu...... Let us create a 'room' for Hashem here with us in galus & with that may we merit to return 'home' with the rebuilding of Avinu Malkeinu's palace b'mhairah b'yameinu.
