Jamieson, Fausset & Brown, on 1Cor 14:14

“For if I pray in a tongue, my spirit prayeth, but my understanding is without fruit.”

“spirit--my higher being, the passive object of the Holy Spirit's operations, and the instrument of prayer in the unknown tongue, distinguished from the "understanding," the active instrument of thought and reasoning; which in this case must be "unfruitful" in edifying others, since the vehicle of expression is unintelligible to them. On the distinction of soul or mind and spirit, see Eph 4:23; Heb 4:12.”
