While we are unable to attend Mass or receive Our Lord in Holy Communion, we can participate in live-stream Masses, or reflect on the daily readings, and make an Act of Spiritual Communion:
My Jesus, I believe that you are present in the most Blessed Sacrament.
I love You above all things and I desire to receive You into my soul.
Since I cannot now receive You sacramentally, come at least spiritually into my heart.
I embrace You as if You were already there, and unite myself wholly to You.
Never permit me to be separated from You. Amen.
