"Of ourselves, we cannot communicate worthily. We need the help of the Holy Spirit. Even though we approach the altar free from mortal sin, He must sharpen our spiritual apprehension and inflame our love to intense ardor, that Christ may find in us a more beautiful habitation every time we receive Him.
The sacramental God has a divine right to expect on our part after each Holy Communion an intensification of our gradual growth into His likeness. As often as we receive Him, He would have us burn with the desire for greater progress in virtue that will manifest itself in an irrevocable detachment from the world and a more unselfish love of Him, grounded on the conviction of our nothingness and consequent sore need of Him.
With greater joy will He abide in us if He beholds us by degrees assimilating His life, resembling Him in virtue by more complete conformity to His will. Christ will unite Himself most intimately with us if we are constant in our effort to imitate Him.
And all this is the effect of the direct operation of the Holy Spirit, who beautifies our souls with His holiness, and adorns them with His invaluable gifts. Being one with Christ, He traces in us the image of our Savior, for only by His power does the mind that is in Christ become the mind that is in us. Thus does He unite us with the sacramental God in the bonds of a common love. And because He is the Spirit of love, He stirs to the depths the love of the Eucharistic God, and moves us to reciprocate it whenever we approach the banquet of the Lord.
Reflecting, before Holy Communion, on the essential, intimate association of the Holy Spirit with the central mystery our Catholic Faith, we will beg Him to remove far from us whatever would impede our reception of the fullness of the grace of this sacrament. We will do more. With an ardor that dilates our hearts with exquisite joy, we will constrain Him to ennoble our thoughts and desires so that we may embrace Christ with a faith that moves mountains, and with a love supremely sacrificial. Then will we glorify our hidden God, and our souls will be His home until the shadows flee away, and we return with the garnered fruits of infinite, eternal love, to contemplate forever, the inexhaustible beauty that we adored under the Eucharistic veil."
