Several years ago, I realized that the modern Synagogue had lost this spiritual art, and that, under the influence of radical thought which minimized Emotion and Sentiment, and exalted Reason and Logic, the average Jew of to-day was losing his prayerful sense. Some factor is missing in the modern synagogue, and I have concluded that it is the art of genuine prayer in its real influence on everyday life. Once this art is restored, our places of worship will he again filled by genuine believers in the power of prayer. Our people will turn once more to "The Living God" as in the days of the Psalmists, and Prayer will be restored to its pristine place. It is my fervent hope that this work on Jewish Science will assist in the work of spiritual renaissance. When once circulated and understood, the Jews of to-day will learn that their own religion offers them a complete cup of salvation. Moreover, this special compilation bearing the hall-mark of Judaism will form a useful hand book of Divine Healing, for the Jew who seeks that truth, as well as for the devout and God-fearing Israelite. To the purpose of making Judaism a living reality and an ever-present help this work is dedicated, with the pious prayer that in the language of our fathers it may be "Le Shem Shomayim" or "In the Name of God."
