After prayer and sacrifice, the most effective means of obtaining from God the grace to form people of deep interior life, which are to rebuild the world, is the spiritual direction. No man is capable of being his own guide. Everyone has weakness to overcome, attractions to keep in order, duties to fulfill, dangers to undergo, occasions of peril to be avoided, difficulties to overcome and doubts to resolve. If one needs help in all this, a fortiori he will require it in his struggle for perfection. It would be an omission, and sometimes a grave omission, in a priest, bound by his duty as teacher and surgeon of souls, if he were to deprive them of this great supplement to confession, this indispensable source of energy for the spiritual life, which is spiritual direction.
