I love to read the poems of Rumi and other Sufi poets. Although the words of love are dedications to God it is possible for more secular interpretations to be made. I am happier with the original expressions of faith.

“Sufism and the encounters that Sufism facilitates –encounters with God, love, and the deepest aspects of human consciousness– have evoked feelings in Sufis that have poured out through their ravaged hearts onto their lucid tongues, providing us with some of the most beautiful and profound poetry ever written.”
