Soul is consciousness and intelligence, or more exactly, higher consciousness. “Higher” means a higher dimension or level of energy. The soul is consciousness expressing as love, wisdom, and unity. The soul is inherently conscious of its unity with all other souls. though most persons have only a glimmer of that reality yet by spiritual evolution this consciousness grows.
Soul is the true identity or what we should mean when we say “I.” that is were we speaking from the deepest source of our nature. But when most say “I” they refer to some combination of the body, mind, and emotions with which they are identified. But these three are only very partial extensions or representations of the soul. The personality borrows its sense of “I” from the soul. Spiritual Self-realization makes this relationship self-evident. So, while in incarnation, the soul is the consciousness that functions and expresses a small part of itself through the mind, emotions, and body.
After death and between incarnations the soul has only the mind and emotions as its vehicles of expression. The soul is the coherent and persistent energy field or aura that is evoked by the interaction of spirit and matter. It is that essential consciousness and individuality that reincarnates down through the ages.
The soul is all this and much more, because the soul is not entirely definable in intellectual terms since it transcends the personality-mind (with its terms and concepts) and can only be deeply understood by direct mystical experience.
