But the teaching that Fr Dubay synthesized is not collected from Teresa and John for contemplatives alone. It is meant for every Christian and is based on the Gospel imperative of personal prayer and the call to holiness. All the major elements of these great teachers are ordered, commented on and put in the context of their scriptural foundations. Here is an outstanding book on prayer and the spiritual life written by one of the best spiritual directors and retreat masters of our time, and based on the writings of the Church's two greatest mystical doctors.
