This difference between the Line and the Sefirot is also seen in the soul and the body. The body is divided into different limbs and organs, and the nature of one limb is not like that of another. However, the soul is all one. We cannot say that the part of the soul in the nose is not the same as the part of the soul in the arm.
The entire soul exists equally in every part of the body. It is only the actions of the soul that vary according to the bodily parts involved, but the entire body is governed by one and the same soul. This means that the soul governs all the different actions of the body without itself changing in any way. The Line is like the soul in the body, for as explained earlier, the various powers are divided up in the Residue like bodily limbs, but the Line governs it like the soul. If so, the Line must be the same on all levels.
