VaAvaditem Es Hashem Elokaichem 5736, Class Two.
Avoda Tzorech Gavoha in this Ma’amar is the Bittul and Mesiras Nefesh in Davening (called Avoda) but also in Torah (connecting Torah with Ein Sof).
But we only start the process through Bittul which is like מילה חיצונית- ומלתם את ערלת לבבכם which Hashem finishes through a higher Bittul מילה פנימיות- ומל ה’ אלוקיך.
This is tied into the idea of דירה בתחתונים, we affect bringing Him down [(as the conclusion of עבודה צורך גבוה) not only until Atzilus, but] until Asiya.
The Rebbe concludes by explaining the words את מספר ימיך אמלא that we fulfil all of our Levushim (time space etc).
