ψυχή (psychē)

The Greek word ψυχή (psychē), according to Thayer's lexicon, means:

 “that in which there is life - a living being, a living soul - the soul - the seat of the feelings, desires, affections, aversions - the soul as an essence which differs from the body and is not dissolved by death (distinguished from other parts of the body)."

"The (human) soul in so far as it is constituted that by the right use of the aids offered it by God it can attain its highest end and secure eternal blessedness, the soul regarded as a moral being designed for everlasting life - the soul as an essence which differs from the body and is not dissolved by death (distinguished from other parts of the body)”

Thus the word is not speaking of the "soul" as if it is some kind of moral organ or possession. The word refers to the spiritual self. This is the eternal self who occupies the temporary physical body.
