At the live-streamed "All School" Mass earlier, I recited the Act of Spiritual Communion of St. Alphonsus Liguori. Here is the prayer:
(Click link below to watch Mass Video)
I believe that you are present
in the most Blessed Sacrament.

come at least spiritually into my heart.
I embrace You as if You were already there,
and unite myself wholly to You.
