Among manuals on the life of prayer, the chapters on prayer from
Jean-Nicholas Grou's School of Jesus Christ stand out as one of the best
short expositions of the essence of prayer that have ever been written.
Like such other great writers on prayeras William Law, Henry Martyn and
Charles de Foucauld, Grou emphasises the importance of mental discipline
for the healthy life of the soul. These simple but effective
instructions are the ripe fruit of the author's long life of prayer and
meditation. Translated by Joseph Dalby.
