As pictured on the Tree of Life, these levels are:
Neschmah, which is itself divided into three parts
Yechidah (the superego), centered in Kether, is our Divine Self
Chia, centered in Chokmah, is our True Will
Neschamah, centered in Binah, is our Intuition
Ruach (the ego), consisting of Chesed, Geburah, Tiphareth, Netzach and Hod, is our Mind
Nephesch (lower self) centered in Yesod is our subconsciousness
Guph. The lowest part of the soul, centered in Malkuth. A low level of subconscious intelligence allied to the physical body. The autonomic nervous system.
