From the editor's preface, "This important treatise unvails, in few but telling words, the nature of prayer, about which mankind has made most awful mistakes. Multitudes conceive that the heart-searching God can be influenced and propitiated by eloquent words and forms of prayer; whilst the few, who are taught by the Holy Spirit, feel and know that the ardent desire, the aspirations, the fervent wishes of the mind, can alone be accepted by the Eternal; and even then only through the merits of the Redeemer."
