The human soul consists of three major faculties

The human soul consists of three major faculties: the physical, the spiritual and the intellectual. The Rabbis call these, respectively: ,רוח, נפש נשמה,ruach, nefesh and neshamah.

— from The Air Traffic Controller (God)

In the book

What we call the neshama, the soul, is a very breath of God, lent to you to be shaped over a lifetime; it has its own levels and its own sanctity, and it is the part of you that does not wear out. Its faculties are braided together — the physical, the emotional, and the intellectual as one — and Maimonides taught the humbling order of it: you cannot perfect the soul while neglecting the body that houses it, for the one is the ladder to the other. We are balanced, always and a little awkwardly, between the spiritual realm above and the physical world below, born with both a body that leans toward its pleasures and a soul that strains upward. — The Air Traffic Controller (God)
