The Life of Prayer, A. B. Simpson (from the preface: "I have read and reread Dr. Simpson's book The Life of Prayer with the deepest interest and profit. No one can give this little book a careful reading without realizing that the author has lived in the secret of his Master's presence. Every page makes it evident that here is a man who has prayed through. Down through the Christian centuries few men have had greater prayer results. Great would be the spiritual quickening if every Christian mastered this classic on the prayer life." -- Jonathan Goforth)
Method of Prayer, Madame Jeane Guyon (I also highly recommend the editor's preface)
