Pope Benedict XVI's General Audience Catechesis on St. Anthony of Padua is worth reading in full but try this part on prayer on for size:
"...St Anthony speaks of prayer as of a loving relationship that impels man to speak gently with the Lord, creating an ineffable joy that sweetly enfolds the soul in prayer. Anthony reminds us that prayer requires an atmosphere of silence, which does not mean distance from external noise but rather is an interior experience that aims to remove the distractions caused by a soul's anxieties, thereby creating silence in the soul itself. According to this prominent Franciscan Doctor's teaching, prayer is structured in four indispensable attitudes which in Anthony's Latin are defined as obsecratio, oratio, postulatio, gratiarum actio. We might translate them in the following manner. The first step in prayer is confidently opening one's heart to God; this is not merely accepting a word but opening one's heart to God's presence. Next, is speaking with him affectionately, seeing him present with oneself; then a very natural thing presenting our needs to him; and lastly, praising and thanking him. (Italics mine)
In St Anthony's teaching on prayer we perceive one of the specific traits of the Franciscan theology that he founded: namely the role assigned to divine love which enters into the sphere of the affections, of the will and of the heart, and which is also the source from which flows a spiritual knowledge that surpasses all other knowledge. In fact, it is in loving that we come to know.
Anthony writes further: "Charity is the soul of faith, it gives it life; without love, faith dies" (Sermones Dominicales et Festivi II, Messagero, Padua 1979, p. 37). "
