As a Bantu saying goes, "My friend is not dead, as I am alive," I can correspondingly say, "My forebears, my brothers and sisters in humanity are not dead, because I have been a penitent to get a soul, be made a God (Rev of Arès 2/13) and, if  I rekindle my soul = my image and likeness of the Creator, I will succeed in saving them, saving the world (28/7)."
The intellect is indiscriminately named soul, or mind, or spirit by rationalists, because they see it as one and the same brain function. The mind admittedly partakes of the intellect; it is an invisible tool of the flesh just as an electroma-gnetic wave is an invisible tool of the radio, but the soul partakes of absolute Life (Rev of Arès 24/5), a premise of which it is from this world's days onwards.

It turns out that for the time being I mortify myself (Rev of Arès 33/34) for three persons lately deceased: nefew Philippe, sister Andrée, sister Chantal, but others join us by night when I pray with them, because there are infinitely more disembodied people than embodied ones in the space, and even I do not mention angels! I cannot see or feel the souls, which are weightless, immeasurable, intang­ible, invisible, inaudible, abstract. Energies? Consciences? Plain qualities? The three of them they are probably. They are as mysterious, real and present as the Wholly Other or life most certainly. Like Him, or like it, they are everywhere, over there in the infinity or right next to my shoulder. In other words I know almost nothing about them.

In a human being, as long as the heart beats, the soul exists in a man or woman, that has made it for himself or herself (Rev of Arès 17/3), just as art exists in the artist. You cannot tell a clear white man (Rev of Arès xvii/12), that has a soul, from the artist, that has art, whenever you pass him or her in the street. However, a soul always arises out of Good, that deifies and eternizes the creature, whereas an artistic work arises out of the mind, even a genius's masterpiece is at best felicitous and may sometimes generates evil. Good is not  necessarily the outcome of the mind's production. The overlap between the mind and the soul has arisen out of the fact that men have forgotten to tell them apart.
Men need souls to make Life just as they need artists to make Art.
The soul is invisible but as real as strength or gravitation and it results from the work of Good or from Good achieved.

Among a lot of features there exists an especially noteworthy feature throuch which The Revelation of Arès removes us from religion and sends us back to the genetic spiritual life, which makes us proceed from Life again.  This feature is the soul, but man has to want it, grow and develop it; working on oneself to create one's soul is called penitence in The Revelation of Arès.
Just as every Arès Pilgrim knows and every ripe corn ear or potential Arès Pilgrim presumes, to be a penitent means to live up to love, forgiveness, peace, and to reason with intelligence spiritual and utterly free from fear and prejudices.

To be penitent enables anybody to create a soul for himself and so doing not only find salvation on death day, but also become a co-creator together with the Creator. Indeed we can change the world (Rev of Arès 28/7).

Jesus called the soul the soul in 1974. The Father called it the ha en 1977. The h is silent; I added it to save readers from mixing up ha with the English indefinite article a  (and a = has and à = at or to in French).
My soul or ha, when I die, will be the sail thanks to which I will join the Heavenly Fleet (Rev of Arès 17/4). Should I fail to become a good man or a penitent, so I should be deprived of a soul, I would be but a specter roaming through the frozen darkness and be more miserable than the blind worms in the depths of necropoles (Rev of Arès 16/15, 4/7), that is, nothing but  a corpse  rotting in a graveyard. But if I have got a soul, it will survvive and I will turn into a scrap of the global Sanctity, Might and Light (Rev of Arès 12/4), an element of the Creator's Power.

What is the soul as a substance? I do not know it any more than I know what substance God is made of. But as true as God exists, the soul exists. My soul is my reciprocity in Good just as I am the reciprocity of God in the world —  Genesis 1/26-27 states that I am the image and likeness of the Creator.
What little I know about my soul I know only through The Revelation of Arès : My soul has not been brought forth by my mother's womb (Rev of Arès 17/3) ; it is the produce of the Good that I have achieved  (31/6) by penitence (30/11).
There is no word for soul in the Bible. The Hebrew word nefeš (= throat) is usually translated by soul, but actually means breath, vital force, (human or animal) life, live being, even person at times. When bound to a personal pronoun nefeš means I, you, he, etc. Nefeš is a vital element, but not an immortal one.  From the Gospels nefeš is translated by Greek ψυχή (psyche) with either a biologic sense or the meaning of life surviving death and prone to be rewarded or punished. The notion of immortal soul is very crude in the Bible.
The Quran, for its part, mentions three kinds of soul : The soul as the instigator of evil (ammâra), the soul that is forvever reproaching itself (lawwâma), the soul appeased and back to God, contented and approved (Mutma'inna, Sura "The Dawn" 89/27-28). The gap is less wide between the Quran's and The Revelation of Arès's soul, but they are not the same, yet
I would rather not dwell on the concepts of the soul in other religions, notably in the Far East.

There you are, I have just said all I know about the soul. That is not much, but that is reliable, as I have got it from the Father. Which is not what the authors that deal with the soul say. I have just read "About the soul" by François Cheng. I have been very pleased to read the handsomely written book. But what new has it told me ? Nothing. With much talented culture the book relates all that thinkers have thought of the soul ever since antiquity: Leozi, the Tao, Buddha Shakamyuni, Plato, Aristotes, Maimonides, Pascal, religions, Simone Weil among many. I have seen what I had seen already, that is, that no thinker or religion has considered the soul as the result from the Good achieved by the human being that owns it. Only The Revelation of Arès reminds mankind of this fundamental.
All men on earth have forgotten what the soul is; it is an entity that any human who has stopped sinning (Rev of Arès 30/11) knowingly or unknowingly adds to his or her native entities, which are the flesh and the mind. So does the incomplete man becomes complete (17/7).
It should be noted that even unbelievers may be haunted by remorse torments. Every day news says that atheists themselves brood over historical abominations of mankind: wars, persecutions, slavery, colonialism, imperialism, fascism, communism, injustice, exploitation of man by man, destruction of nature, terrorism. They clearly can see a continuity of horrors in parallel to good deeds. Unbelievers maintain their own feelings of remorse as well as urgency procedures against evil when it comes up from anywhere else, just as in days of old  the fire guards looked after the fire, which might be of use to cook the food or heat the house as well as cause disastrous arsons. Why do unbelievers forget about the very plain fact that it would only take a specific education of children gainst evil to recreate the world in love, peace, freedom, good-hearted intelligence, in other words to have a lot of souls coming to life? Why do they forget that men have undoubtedly give birth to barbarians, freaks and finally specters roaming throughout the frozen darkness (Rev of Arès 16/15), but they also have deep down kept the means to change life into bliss?
It is very strange that we nowadays are living through a situation of one-sided repentance, the one that the rationalistic side requires, the side of those who cloak themselves in reason so that they may more convincingly claim that we are just dreamers, cranks, even though we pursue the same objective as theirs. that is, conquering Evil, only by ways different from theirs, that is, not by the law, only by personal efforts to be good, in other words by the soul each one makes for himself or herself through penitence? Therefore, the soul is not the least issue of a tragical contradiction. Unvelievers laugh, because the soul cannot be seen under a microscope? But can the mind, ot remorse, or untruthfulness, or love be seen under it? No, it can't. Remorse (Rev of Arès 8/5), for instance, is nothing but the triumph of the spirit of surrender in the face of History, which unbelievers think is inevitable. We shout to them, No! History is not inevitable! We have to beat it and then start all over again, begin another way of life. The Arès Pilgrims along with all of the good men, the men of the coming time (30/13) are not people repenting of sins, but penitents, human beings with a soul, the best weapon againt evil and death.

Good can triumph over Evil and it draws its Power from the soul or ha. When a combination of the Word achieved (Rév d'Arès 35/6) — Let your Sanctity prevail over us ! (12/4) — and the Will of penitence — so that we do Your Will (12/4) — is fulfilled, the soul or ha is born, added to the force that is building up the future myriad of souls or has, which will some day send the Evil Beast dying below the horizon (22/14). Religion has nothing to do with that. Just live according to the Sermon on the Mount, which has not founded any religion, and you will make a volcano (L/6) of triumphant Good active again. Eden is not a fertile soil Garden (xxviii/21) with trees of wood and flowers of flesh, but Life, that will conquer the Universe, the blooming of the happy Whole.

What can we see in the modern man ? We usually see the thinking animal, that used to sleep on the shadows (Rev of Arès vii/2). But let's bear in mind that he is Adam's son, the offspring of a  race (25/4, xii/5) deified by the Creation. What the Maker changed the animal into a lamp (Matthew 5/15, 6/22) with, a lamp that could produce the Light (12/4), be His Image and Likeness (Genesis 1/26)? With the soul, of course! The soul is God within man. God asks us to rekindle the soul within us, because we possess a part of Himself, and because we share the Life He lavished on us when we piece ourselves together again, Life which is no more than life in the mortal flesh, nothing bit the shadow of Life. Then an infinite Bliss follows on from it, the Father's Bliss along with our bliss, which are as One (xxiv/1). The Revelation of Arès's Vigil 17 is fundamental on this point. Mankind en masse is empty wheat (xxvi/8). The good wheat (xx/19) has become scarce, it is the ripe ears, those that can get a soul. But a soul is stronger than a thousand minds and fleshes without souls. Our mission has forever been striving to find the penitents who are going to save the world.
