Yes.. I read of this more than once.. prayer is communication.. but we, our whole selves can communicate.. not only the words... all of our beings..
When our entire self communicates with God purely.. that truly is Communion.
Whatever pieces of ourselves we can offer, however quickly or slowly, there are all sorts of pieces.. we offer them.
What we want to offer are pure intentions, pure deeds.. a pure and perfect offering. Which only Christ in us can enable us to make.
I love Sirach especially by the way.
