I have an engineering approach to body/soul concept. It is not religious at all. It's more along the lines of Freud and the super-ego or Teilhard de Chardin and the noosphere. That is, there are three levels, two of which are invisible yet just as real as the material body. The mid level would be the soul or spirit and it is that part that is the function of the mind, the 'I' inside the body. The higher level is the functioning within nature and society, operant behavior or the ability to modify the enviroment. We might draw an analogy, imperfect as analogies always are, to (1) the computer hardware, (2) the software [which includes any necessary data] loaded in the CPU , and (3) the functioning of the program.

You might find it interesting to read a book by James Kennedy, title (I think) Teaching Through The Tabernacle. In this book, Rev. Kennedy parallels the construction of the Tabernacle to the way God constructed humankind, with the outer court representing the body, the inner sanctum the soul, and the Holy of Holies the spirit. The furniture in the Tabernacle has interesting parallels ... the showbread table, the golden lampstand, and the altar of incense, etc., found in the inner sanctum.
