I'd like to share a poem that I found at Heart to Heart Website, an Apostolic Mission for the Renewal of the Devotion to The Sacred Heart of Jesus.
Here's what it says at the site:
Since many of the poems, are ... beautiful prayers of love to Him, it is highly recommended that those who wish to advance in their spiritual closeness and unity with His Divine Heart, recite those that most speak your feelings daily.
Two of His 12 Promises to those who practice the devotion faithfully with great love ... are that: "tepid souls shall become fervent" and that "fervent souls shall quickly mount to high perfection." After you read them, slowly, as prayers, we believe these poems will present His love ... to you in a way you have never before ... experienced Him and the enormity of His love and sacrifice for us all. Feeling this, we are confident that you will reach a higher level of unity with His Heart ....
