The author in his commentary offered road signs (cards) as to the pathway of life. No doubt the author took his cue from Jesus who said, "I am the way, the truth and the life." Translated, take the truth and apply it to life and you will be on the way. Prescott and his treatise mentioned the attributes of the Christian life; thus carrying out what the author had in mind when he used INNER MIND MENDER which is thus the spirit of the mind.
