Nothing...and I mean nothing moves me more than meditating on the Heart of Jesus. In the early years of my prayer life I was so consumed by this that I started uniting my heartbeats with his. When I couldn't find time for prayer I would simply unite each beat of my heart with each beat of his. This proved very fruitful for me as Jesus' Heart was always in the forefront of my thoughts. I do this before I go to sleep, too. As a matter of fact, it's such a given at this point that when I hear my heart beat I think of Jesus. By uniting our hearts in this manner I have received "grace upon grace" without letup. Jesus is the Gate of Heaven through which we all must enter:
The Sign of the Cross
O Most Beautiful Gate
O heart Divine
Upon Thy Portal
Is nailed a sign
All who would enter
Whom the Father shall see
All who would enter
Must enter through Me
