and the contemplation of the mysteries or episodes of the life of Christ so illumine the mind and inflame the heart that we cannot fail, if we are reasonable, at least to desire to make the love of Christ the dominating motive of our life;and, in view of that end, we are given at every step a new insight into our duties to God, chiefly under the double aspect of our Creation and Redemption;
we are taught to scrutinize our thoughts, tendencies, inclinations, passions and aspirations, and to detect the devices of self-deceit; we are shown the dangers that beset us and the means of safety that are available; we are instructed in prayer, meditation and self-examination.The proper co-ordination of these various parts is so essential, that if their interdependence is neglected, if the arrangements and adjustments are disturbed and the connecting links disregarded or displaced, the end intended by Saint Ignatius is defeated. Hence the need of a director.
