One might say something like this;
Lord Jesus Christ,
my desire and the intention of my heart
is to pray before Thy holy image as if I were in Thy Eucharistic presence.
Transport my soul before the tabernacle where
Thou art most forsaken at this hour,
and there let me offer Thee my desire to adore Thee,
and my love,
in a spirit of reparation.
Or, like this:
Receive this time before Thee
as an act of adoration and reparation directed to Thee
in the Most Blessed Sacrament,
especially in that tabernacle on earth where Thou art most forsaken.
Make me, especially for the sake of Thy priests and for their sanctification,
a faithful adorer of Thy Eucharistic Face
and of Thy Open Heart hidden in the Sacrament of Thy Love.
Trusting that faith, hope, and love abolish every distance
and transport the soul straightway to the object of its desire,
I will adore Thee now with the same sentiments
of thanksgiving, confidence, and pleading love
that I would have,
were I prostrate before the Sacrament of Thy Body and Blood
hidden in the tabernacle, or exposed to my gaze upon the altar.
