Chapter 4 answers the question that was asked at the end of the previous chapter. How it is that creation is not nullified out of existence before Hashem? The answer is that Hashem's restraining power allows His creative power to conceal itself in a way that created beings can retain a sense of independent selfhood.

In Chapter 3, the Alter Rebbe illustrates how, based on what we have learned in chs 1-2, it is a logical conclusion that all of created reality is non-existent relative to the Divine energy that constantly brings it in to being,

In Chapter 2 of Shaar HaYichud VeHaEmunah, the Alter Rebbe uses the mechanics of the miraculous Splitting of the Sea to give us a logical way of understanding why creation must be constant and continuous.

Chapter 1 of Shaar HaYichud VeHaEmunah introduces the idea that all of created reality is composed of arrangements of the 22 letters of the Holy Tongue and that it is the Divine Speech that issues for these letters that causes all of creation to continue to exist rather than revert into nothingness.

We begin the second volume of Tanya known as The Gate of Unity and Faith (Shaar HaYichud Ve'HaEmunah) which explains the oneness and unity of Hashem. In this introduction, the Alter Rebbe explains why we need to understand this subject matter as it is the foundation to developing proper love and awe of Hashem.

The final class of this series covers Ch. 53 of Tanya.

This lesson covers Ch. 52 in Tanya in which we further explain the concept of the "brain" of each plane of existence that was mentioned in Ch. 51.

Chapter 51 of Tanya takes us back to the discussion of the power of action that came up in Chapter 35 where mitzvos were compared to oil which fuels the flame of G-dly revelation. To better understand this, we ask a question: What does it mean that the Divine Presence rested in the Holy of Holies when we know that there is no place devoid of Hashem?

Concluding the theme of love and awe of Hashem begun in Ch. 41, a new type of love is introduced here in Ch. 50 that is in a whole different category from all previously discussed forms of love.

Finishing Ch. 49 of Tanya and the subject of "reciprocal love." In this class, we deal at length with the idea of Hashem "choosing" the Jewish people.
