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.
