The difference between Rabbi Nachman of Breslev and Na Nach Nachma Nachman from Uman is that the former went back to the Ukraine to leave his bones for us to take to Israel and the latter finished the job, he is also Rabbi Nachman...true he finished for himself, however, only Am Israel can really finish the job (of keeping their old oath).
The Nachman(s) "came" to Israel however (the title Ki Tavo means "because you will come") in Rabbi Nachman of Breslev's case it was similar to Josef, he only came to ensure his future burial and perhaps to keep a promise common to all Jews (after having made four steps he wanted to go back, being obligated to stay he attempted to go to Jerusalem but he was prevented from doing so).
The Ki Tavo speaks of the Cohen of that day and the place where his NAME will reside and special instructions about the Bikourim which in Hebrew also means "visits" but no one notices it. Because each visit to a new Jew brings first fruits of Torah and new wisdom and insight. I call this Hafatsa.
We have typical blessing and curse situation, related to the opening and closing of a period. Entering the 40 desert years we received the 10 commandments now leaving that period we receive the 10 curses. Entering the Diaspora we take an oath to bring Josef to Israel when G-d remembers us, we didn't exactly keep our covenant our "bris mila" so we are still in the diaspora. What about the promise made to Abraham that we would spend 400 years in Egypt. This covenant was also made "between" parts (like the two mountains or the two tablets) with a clear beginning and end of the period. The focus of this Ki Tavo are 13 curses separated by 10 Amens (like the 10 commandments) marking the closing of the episode of the spies. AMEN folks means Bring Your Life (French/Rashi language) the Loyal King of Truth (Hebrew) uniting the brother of the Torah to the Torah you can put the two statements together and solve the riddle. The 10 laws here are very different from the 10 commandments. They are absolutely relevant to the more "modern" teachings of Rabbi Nachman and give you an idea of what the Cohen of this new place wants to hear, because as rabbi Nachman says wisdom can only be attained by the pure, the offerings given in this place are holy teachings, the fruit of human struggle to come closer to G-d in the land of truth.
I hope you were able to absorb this fresh look at Ki Tavo which goes far beyond the current teachings of those who have the misfortune of not understanding anything about Na Nach and the Petek.
