Why pray? Padre Quadrupani remarks: “We ought to love meditation and should make it often on the Passion of our divine Lord, striving above all to derive therefrom fruits of humility, patience and charity.”
How often? “It is well to bear in mind that in commanding us to pray always our Saviour did not mean actual prayer, as that would be an impossibility. The desire to glorify God by all our actions suffices for the rigorous fulfilment of this precept, if this desire be habitual and permanent. ‘You pray often,’ says St. Augustine, ‘if you often have a desire to pay homage to God by your actions: you pray always if you always have this desire, no matter how you may be otherwise employed.'”
When? “You should never omit or neglect the duties of your state of life in order to say certain self-imposed prayers. These duties are a substitute for prayers and are equally efficacious, St. Thomas teaches, for obtaining the graces you stand in need of and which are promised to those who ask them properly. It is even more meritorious to perform some work for the love of God, to whom we offer it, than merely to raise the soul to Him by actual prayer.”
How? “Prepare yourself for prayer by peaceful recollection and begin it without agitation or uneasiness. St. Francis de Sales has this to say on the subject: ‘Some little time before you are going to pray, calm and compose your heart, and be hopeful of doing well; for if you begin without hope and already devoid of relish, you will find it difficult to regain an appetite. . . . The disquiet you experience in prayer, accompanied by great eagerness to discover some object that can fix and satisfy your thoughts, is of itself sufficient to prevent you finding what you seek. When a thing is searched for with too great eagerness, one may have his hands or his eyes almost upon it a hundred times and yet fail to perceive it. This vain and useless anxiety in regard to prayer can result in nothing but weariness of mind, and this in turn produces coldness and apathy in your soul.'”
Advice on spiritual body language: “St. Theresa’s opinion is that the body should be in a comfortable position when we pray, as otherwise it is difficult for the mind to pay the proper attention to prayer and to the presence of God. Do not then fatigue your body by remaining too long prostrate or kneeling: the important thing is that the soul should humble itself before God in sentiments of respect, confidence and love.”
