Here, the refers to the original monadic intensification, god with a little "g", from which all of creation emanates. "From this Soul (Atmam), verily, space (akasa) arose; from space, wind (vayu); from wind, fire; from fire, water; from water, the earth ; from the earth, herbs ; from herbs, food ; from food, semen ; from semen, the person."ref>Hume, Robert Ernest, trans.

Here, generically to Spiritual Ego. "The Self (Atman), which is free from evil, ageless, death- less, sorro\vless, hungerless, thirstless, whose desire is the Real, whose conception is the Real" 
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.
"Atma of the Hindus is the unchangeable Reality, the Great Witness, Consciousness Itself, Sakshi Chaitanya."
Atman is an egoic instantiation in the Fabric of Consciousness. Atman is visually represented as an "eye" in the Tree of Lights.
