Circumcision of the Heart

In Parshat Nitzavim, Moshe Rabbeinu foretells the return of Am Yisrael to Eretz Yisrael after the fulfillment of the blessings and curses of Parshat Ki Tavo. I'd like to focus on two verses:

דברים ל:ו - ומל ה' אלהיך את לבבך, ואת לבב זרעך, לאהבה את ה' אלהיך בכל לבבך ובכל נפשך למען חייך

דברים ל:ז - ונתן ה' אלהיך את כל האלות האלה על איביך ועל שנאיך אשר רדפוך

Devarim 30:6 - And Hashem, your G-d, will circumcise your heart, and the heart of your offspring, to love Hashem, your G-d, with all your heart and all your soul, for your life's sake.

Devarim 30:7 - And Hashem, your G-d, will give all these curses upon your enemies and those that hate you, that pursued you.

It seems to me from here that the term "circumcision of the heart" is related to Ateret haYesod. Therefore, this is a teaching that after the Zechirah begins, the נקמה taken by Moshiach begins. This is brought in Ma'amar haGeulah, for anyone interested.
