Note: I don’t remember the exact wording because I didn’t write it down immediately, but it was like this:
Remember to make Spiritual Communions. Do this (at least) once daily. Remember Me.
Here’s one version:
Act of Spiritual Communion by St. Alphonsus Liguori
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 at this moment 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.
