The Soul Ruach (רוח) covers all the Sephiroth involved in the world Yetzirah: Chesed, Geburah, Tiphareth, Netzach, Hod, and Yesod.
The souls are divided from one another by veils. Above this group sits the Abyss, separating it from our higher consciousness, Neshamah. Below it sits the Veil of the Profane, separating it from the gross physical world of Nephesh. And within this soul there is also a veil, Paroketh.
