The goal is to achieve union with the Lord, and the Holy Eucharist makes it possible if you'll let it do the work. Receive the Lord in the Holy Eucharist with great reverence and all your love, and ask him to transform every part of you, every fiber and molecule of you, with his love. Then think every thought, speak every word, and do every deed as one with the Lord. You are now starting to live in heaven. When you get there, there won't be much adjustment you'll need to make.
