This is a great prayer to say before receiving the Eucharist at Mass. It's a beautiful acknowledge of the gift we are about to receive.
O Jesus, as I approach Your altar to receive You in the Holy Eucharist, let me desire nothing but Divine Union with You. Stand guard over my heart. Defend me against all distractions and attacks against my faith. Help me in my imperfect love to return love to You. Amen.
