That a Devout Soul Ought to Desire, With the Whole Heart, to be United to Christ in This Sacrament

For this I pray, this I desire, that I may be wholly united to You, and that I may withdraw my heart from all things created; and by Holy Communion, and often celebrating, I may more and more learn to relish things heavenly and eternal.  Ah, Lord God, when shall I be wholly united to, and absorbed in You, and altogether unmindful of myself?...You are in truth a hidden god, and Your counsel is not with the wicked, but Your conversation is with the humble and the simple.  Oh, how sweet, O Lord, is Your Spirit, who, to show Your sweetness towards Your children, vouchsafes to refresh them with that  most delicious bread which comes down from heaven!...But what shall I render to the Lord for this grace, for charity so remarkable?  There is not anything that I can present to Him more acceptable than to give up my heart entirely to God, and closely unite it to Him.
