Atman (आत्मन्) is a sanskrit term syncretic with Spiritual Ego.
Spiritual Ego > Atman, Augoeides, Buddha Nature, Genuine Self, Great Self, Higher Self, Highest Self, Holy Spirit, Immortal Spirit, Inner Self, Inner-Self, Monad, Monadic Intensification, Ohr, Original Face, Resident Monadic Consciousness, Self, Soul, Spirit, Super Ego, The Witness, True Self, Universal Being, Universal Self
If the Wikipedia entry is any indication, there is considerable confusion surrounding the term with it being used sometimes to refer to Monadic Consciousness, sometimes to the Fabric of Consciousness before Instantiated Awareness, and sometimes even the "defiled self" (i.e. Bodily Ego). Here we will confine the term to mean the Instantiated Awareness of Monadic Consciousness.
Atman is an egoic instantiation in the Fabric of Consciousness. Atman is visually represented as an "eye" in the Tree of Lights.
