For reference, this question asks whether there is a difference between the soul and spirit.
Assuming that your spirit is the heavenly nature of man, is the soul the same thing as mind, as in personality, temperance, intelligence, conciseness etc?
We tend to think of the soul as the eternal part of a person, as opposed to his temporal part:
The explanation is to be found in this Free Grace article.

The article was written to refute the view that good works saved the believer's soul.
Wilkins, author of the article, wished to show that "save your soul" could mean "preserve your life".
The categories to differentiate between are spirit and soul . Some explain the first as what you have, the last as what you are. IOW, God could reward you for having a beautiful soul, character, but not for having a long life (long being the desirable quality in generic lives), since it is what He Himself gives.
Similarly, the mind is what He gives, but the soul is what you make of Life, when used to mean person. It could also be what God preserves, when used to mean life opportunity, permission to continue living.
If you do an in depth study of the the Greek on 'soul' and 'spirit' they are essentially the same thing. However they are different is that one is viewed heavenward, and one earthward. The soul is the essential life of man ‘looking earthward’ and the ‘spirit’ that same principle of life breathed (like wind) into man from God, that can look towards and experience God. I say 'can look' because the whole spirit/soul, including mind, emotions and will, the higher, as well as lower powers of our nature, are the seat and subject of original sin. The 'natural man' is thereby disabled and made opposite to all spiritual good. Consequently the conflict of which the Scriptures speak between the higher and lower powers of nature,—is between nature and what is not nature, between the old and new man. The new principle is something supernatural communicated by the Spirit of God. The new man is called spiritual rather than soul-ual, because it is the essential nature of man looking heaven ward called 'spirit'.
You can see these ideas at work in this passage. Just as the soul 'thinks' so the spirit 'thinks'. That is, mind is both representative of the soul and the spirit as part of our essential life. The spirit is not of a different nature of the soul, the are the same, only under a different perspective. Only your spirit/soul knows your thoughts. Also receiving the Spirit of Christ is the same as receiving the mind of Christ:
For a deeper analysis of the subject one can refer to trichotomous versus dichotomous views of man.
