I just picked up an interesting tidbit from the latest book I'm reading, Medjugorje Prayer Book: you'll only get out of Mass what you bring to it.
The portion of the book I just read has excerpts from a locutionist, someone who hears Jesus's words through her heart (but doesn't experience an apparition), and this is what she relayed:
"Just as with every time you come to receive me in the sacrament of the Holy Eucharist, I again give you My whole being. Do you desire to remain in darkness instead of in My Light? Why do you continue to disregard Mine and My Father's gifts to you? I love you, my children. I AM your Jesus of Mercy."
