Psyche
So for Freud, the psyche or the mind consists of a structure
composed of three units: the id, which is the reservoir of all
instinctual forces and energies, and which is merged with the
physical organism; the ego, which forms mostly the functional
self that is in direct contact with the external world; and the
superego, which is the moral and ethical element of the ego. (The
Void, pg 5)

The soul—called “psyche”—comprised
all of one's subjectivity, including what we now call mind, heart,
spirit, consciousness, will and so on. (The Inner Journey Home)

Soul appears mostly in the field of humanities, especially
in that of psychology, but as the study of and work with the
psyche or self, and its inner mechanisms and manifestations.
God is the focus of religion and spirituality, and when this
is cast in the form of the study of 'Being' it becomes also a
subject for philosophy. Cosmos or world is exclusively the concern
of physical science in its various specializations. (The Inner
Journey Home)

Psyche & Self
What is conventionally known as the psyche is part of this
self. The mind is part of the self, manifesting the capacity
to remember, to think, to imagine, to construct and integrate
images, to discriminate, analyze, synthesize, and so on. The
feelings are part of the self: the capacity to desire, to choose,
to value, to love.
