Question: Why is fear the first Mitzva that includes within it all the Mitzvot of the Torah?
Answer: Fear is a characteristic of Malchut reached through the desire to receive. If I work with the desire to receive in order to correct it, I am standing on the right point from which I can always begin. Every level begins from fear. Every time I fall and begin to build the next level, I first experience all kinds of fears.
Question: If I fall, then I fall. Why must there be fear in this?
Answer: First it is necessary to clarify what is called falling. If you have a bad mood or a bad feeling, this is not a fall. A fall is an inability to approach the Creator, to bestow to Him. I fall if I lose interest in the friends, the desire to be with them, and to feel the warmth and closeness in our connection. Everything depends on this according to what I check regarding my fall.
I feel bad because I don’t have love for others, and from this I don’t have love for the Creator. It is specifically this condition that I establish as a descent. When I come to a group, I don’t feel any desire to connect with the friends to discover the love between us that is called the Creator.
If I perceive that I don’t have a desire like this, this is already good; this indicates that I am in exile. Attaining exile is a great attainment because I see that “there is no divinity within me” (Devarim 31:17).
