The great spiritual classic, The Imitation of Christ, suggests the following sentiments in the presence of Our Lord in the Blessed Sacrament:
The most devout King David danced before the ark of God with all his strength as he recalled the benefits once bestowed upon his fathers. He made musical instruments of many kinds. He composed psalms and ordered them sung with joy. He himself often played upon the harp when moved by the grace of the Holy Ghost. He taught the people of Israel to praise God with all their hearts and to raise their voices every day to bless and glorify Him. If such great devotion flourished in those days and such ceremony in praise of God before the Ark of the Covenant, what great devotion ought not I and all Christian people now show in the presence of this Sacrament; what reverence in receiving the most excellent Body of Christ! - Book Four, ch. 1
