Tanya Chapter 1 part 3. Getting to know the origin of our first soul, unveiling the secret of the tree of knowledge of good and evil

Let's explore the first soul, the one that vitalizes our body and is clothed within our blood. It originates from the klipah and sitra achara, the realm of unholiness, and is made of the four evil elements that give rise to our negative qualities and character traits. Surprisingly, this soul is also the source for the natural Jewish traits of kindness and compassion. This is because it stems from the "glowing klipah" –– kelipat nogah –– which contains both good and evil, flowing from the esoteric tree of knowledge of good and evil. The distinct inclination of the Jewish animal soul towards altruistic goodness is unique to them. On the other hand, the natural soul of most people from other nations originates from the three completely impure kelipot, which obscure any trace of goodness. Consequently, the kindness they exhibit is driven by self-serving motives.
