"And the Lord God formed man [adam] of the dust of the ground [adamah],
and breathed into his nostrils the breath of life [neshamah];
and man became a living [chay] soul [nephesh]." (Genesis 2:7)
nefesh (psyche [Greek] | anima [Latin])
The animal or sanguinary soul
In the Greek Septuagint nephesh is translated as 'living soul' in reference to man, and 'living creature' when referring to animals - the Hebrew makes no distinction, a living thing 'is' a soul, rather than something in the possession 'of' a soul - In this sense nefesh is at the level of biological activity: "for the life [nefesh] of every creature is the blood of it," (Lev 17:14) or "for the blood is the life [nefesh]" (Deut 122:23).
This animic soul is not an immortal soul however, for whereas 'chay nefesh' means living soul or creature, 'muwth nefesh' means a 'dead body' or a 'dead soul.'
Ruach (nous/pneuma | spiritus)
The mental soul
The term 'ruach' is used in many senses and can only be properly understood against in the total context of scripture. It means 'breath' (in the anthropological sense) or 'wind' (in the spiritual), and as such can express the principle of animal and all life, although it never designates an individual being, but rather the principle of life as such:
"In whose hand [is] the soul [nefesh] of every living thing [chay], and the breath [ruach] of all mankind," (Job 12:10)
Thus ruach can imply a transcendant, or a transpersonal, quality, and as such we have not necessarily risen above the cosmological. Ruach in reference to the Spirit of God is Divine, but ruach in reference to the spirit of man is not. Further 'ruach' in the human sense can encompass error, "They also that erred in spirit [ruach]" (Isaias 29:44) and this can signify disorder, passion, even madness, "Terrors are turned upon me: they pursue my soul as the wind [ruach]" (Job 30:15), or "Behold, they are all vanity; their works are nothing: their molten images are wind [ruach] and confusion," (Isaias 41:29).
Neshamah (pneuma/pnoe | spiritus/spiraculum/habitus)
The spiritualised soul
Neshamah is the breath, be it human or divine. In Genesis God made man and 'breathed' into him, but the breath of God must necessarily convey more than simple animation. The Divine Breath not only animated humanity but conferred upon it a sanctified state, a state of grace (the descent of the Holy Spirit as 'tongues of flame' continues this idea), our Adamic or Primordial state.
Here great care must be taken to differentiate between neshamah as a natural quality of the human spirit, and neshamah as a supernatural quality infused by the Divine Breath, a situation made more difficult by ther apparent interchangeability of ruach and neshamah:
"All the while my breath [neshamah] is in me, and the spirit [ruach] of God is in my nostrils;"
Job 27:3
Whilst neshamah sanctifies man, it remains in and of itself Divine and forms no part of his individual nature: "The Spirit breatheth where he will and thou hearest his voice: but thou knowest not whence he cometh and whither he goeth. So is every one that is born of the Spirit." (John 3:8)
It is through neshamah we receive our life from God, and it is through neshamah we must also return to Him, "That which is born of the flesh is flesh: and that which is born of the Spirit is spirit," (John 3:6) upon the breath of prayer: "Let every thing that hath breath [neshamah] praise the Lord. Praise ye the Lord."
There are in the kabbala two further determinations - but these are degrees or modes of neshamah:
Hayah
The living soul
An awareness of the divine life force itself.
Yehidah
The one soul
In which one can achieve as full a union with God as is possible.
Both rabbinic and kabbalistic works posit that there are also additional non-permanent states (infused or inspired) of the soul that people can develop on certain occasions. These spiritual qualities play no part in any eschatalogical scheme, but are mentioned for completeness:
Ruach HaKodesh
The spirit of holiness
A state of the soul that makes prophecy possible. Since the age of classical prophecy passed, no one receives the soul of prophesy any longer.
Note: as healing is considered among the Divine Gifts of the Spirit, then I would posit, in accord with Rabbinic, Kabbalistic and Christian doctrine, that the 'realm' of healing is that of the ruach, which locates its function in the greater scheme of things.
Neshamah Yeseira
The supplemental soul that a Jew experience on Shabbat. It makes possible an enhanced spiritual enjoyment of the day. This exists only when one is observing Shabbat; it can be lost and gained depending on one's observance.
Neshamah Kedosha
A spiritual quality related to the study and fulfillment of the Torah commandments. It exists only when one studies and follows Torah; it can be lost and gained depending on one's study and observance.
Note:
These two give a view of neshamah - whilst this spiritual quality is enhanced with regard to ruach, it is still within the human domain, but can aspire or attain to higher qualities when engaged corectly in 'higher' things. The former, 'Neshamah Yeseira' is liturgical (the proper observation of the sabbath) and again 'Neshamah Kedosha' is a state in contremplation of the Divine Mysteries - which again are most present and profound in the liturgy of the tradition in question.
