Seed of man and seed of animal:[1]
There exist two types of Jewish souls, one which is known as the seed of man [i.e. Zera Adam] and another which is known as the seed of animal [i.e. Zera Beheima]. [Meaning, that even within the human Jewish soul, there exists a soul which is on the level of animal, and a soul which is on the level of human, which is of course of a higher level. This matter was discussed in length in volume 1 of our series, in Likkutei Torah Parshas Mishpatim. In short, souls that come from the seed of man serve G-d with intellect and the study of Torah, while souls that come from the seed of animal, serve G-d with emotions of love and fear. The emotions of love and fear are merely the wings that help to elevate the Mitzvah’s while the Torah contains the 248 actual limbs, and is hence higher than the level of wings which is represented in the emotions of love and fear. We will now expand on the concept of a lion in spiritual terms, and how it corresponds to love and fear.
