And know, that with all of this [where his Ruach is enclothed into the Nefesh of the Ger], since his Ruach is connected in this world with him, it helps him and improves his actions and acts as a merkava for him in this world. Through this, the Ruach can rectify itself, but also, the Nefesh of this Ger elevates together with the Ruach, and the two of them remain on the same level in the Olam Haba because they remain as unified neighbors, and they do not separate [after death].
Also know, that sometimes it happens that when the Nefesh reincarnates alone to fix itself, if it completes all of its tasks, raising it to the level that it could be able to receive its Ruach [in theory], in that same gilgul, it is not possible to receive its Ruach, as we described earlier. This is because they (the Nefesh and the Ruach, or the Nefesh, the Ruach, and the Neshama) were not together [at the beginning of] this lifetime. But this is not something to be worried about, as we will explain in another explanation [at the end of Ch. 3]. However, each one can reincarnate alone [seemingly in different bodies, at the same time], as we explained above. First the Nefesh needs to rectified, and after it is rectified, it is impossible for the Ruach to join it [in this life]. So the person needs to die, and the Nefesh can reincarnate (not for its own rectification, because it was already rectified in the previous gilgul). Then, when the Ruach joins the Nefesh [in the next gilgul] and they are both rectified (the Nefesh in the previous gilgul, and the Ruach in this gilgul), it is impossible for him to receive his Neshama (until he reincarnates again). Then (in the third gilgul), his Neshama can join his Nefesh and his Ruach.
