1) The Hebrew word for soul is "nephesh" and it means life.
2) The Hebrew word for spirit is "ruach" and it means breath or wind.
You're as confused as those ignorant Hebrew patriarchs.
Life force and vital airs mean almost the same thing and are aspects of the universal vital consciousness-force.
Life and breath are related terms in a deeper sense.
Besides, the infused life-force animates the physical forces like electromagnetism, matter, and its states - solid, liquid, gas, plasma, gluon-quark plasma, Einstein-Bose condensate and so on.
An aspect of the life-force with its pentuple currents infuses matter and in the body it is known as the physico-vital which gives life and animates the organ systems.
Inhalation of oxygen like the ingestion of food, sleep, touch and other modes of action are ways of replenishing the life-force as it manifests in matter.
The life-force is an aspect of the vital consciousness and the life-force animates matter and draws in life force from the universal life-force currents through breathing in of air, food, touch and rest, as stated above.
Ruach and nepesh are in this way dependent terms and both refer to the vital principle though of course the Hebrews were ignorant of the fact that the life-force was an aspect of the vital and that it (life force) had 5 currents and so on and they were also ignorant of the states of existence that exceeded the vital.
Vital exceeds matter, mind exceeds the vital, supermind exceeds the mind, and so on....
Actually the cosmic hierarchy is as follows:
2) Subtle Physical
3) Lower Vital
4) Higher Vital
6) Higher Mind
7) Illumined Mind
8) Intuition Mind
9) Overmind - 1
10) Overmind -2
11) Overmind - 3
12) Overmind - 4
13) Supermind - 1
14) Supermind - 2
15) Supermind - 3
16) Supermind -4
and so on.....
Everything about the Middle Eastern cults is based on the vital force.
The Hebrews were stuck on the lowly vital plane and their G-d too is a vital being, one being among many, that they chose to worship as they had been taught by the pre-Hebrew seers of the older cultures of the Middle East.
The soul is something else. Read my post on the soul.
Here it is. This is the true meaning of the soul and it far far exceeds the ordinary meaning of soul given by those very ignorant Hebrew patriarchs.
WHAT IS THE SOUL?
1) The soul is the psychic consciousness which is a supporting and organizing grade of consciousness with its concomitant energy that stands behind the mental, vital, subtle physical, gross physical and subconscient layers of consciousness.
2) The psychic is usually smothered in most human beings since perverse mental, vital and physical instincts tend to choke it.
3) Only under certain conditions of balance among the psychological, vital and physical elements and with sustained aspiration and intense concentration on its root vibration does the psychic effulge and come to the forefront.
4) The psychic is a delegation of the cosmic self which in turn is a projection of the supracosmic self and this in turn is a direct line of consciousness put forth by the unified field of consciousness-energy when it manifests.
CONCLUSION: The satan-worshipping, incestuously born and mass-murdering Hebrew patriarchs, our deluded and wolf-in-sheep's clothing, Jesus, and the satanist, inbred and mass-murdering Muhammad had no knowledge of the psychic and its higher gradations. Expected!
