Partie 12 · Chapitre 219

But the main point is that the Nefesh is clothed in the outer vessels, and the Ruach in the middle, and the Neshama in the inner ones. And it is found that in the brain there are NRN (Nefesh, Ruach, Neshama), except that all of them are the aspect of Neshama — namely, the Neshama of the Neshama, and the Neshama of the Ruach, and the Neshama of the Nefesh. Therefore we say that the Neshama is in the brain. Afterwards, in the heart there are NRN, and all of them are the aspect of Ruach — namely, the Ruach of the Neshama, and the Ruach of the Ruach, and the Ruach of the Nefesh; therefore we say that the Ruach is in the heart. And afterwards, in the liver there are NRN, and all of them are the aspect of Nefesh — namely, the Nefesh in the Neshama, the Nefesh of the Ruach, the Nefesh of the Nefesh; therefore we say that the Nefesh is in the liver.
