At first, you chant the Divine Names, then they chant themselves, then God chants through you.
There are many different Sufi practices of remembrance, including silent remembrance, chanting of Divine Names, and group practices of chanting, movement, and music.
Implicit in the term remembrance is the notion that we are coming back to what we once knew, what we have already learned. The Sufis believe that our souls were in the world of souls for thousands of years. There, bathed in God's presence, our souls experienced the Divine more fully and deeply than we can imagine. In practicing remembrance, we are seeking to recapture a small part of that blessed state.— James Fadiman, Robert Frager, Essential Sufism by James Fadiman, editor, Robert Frager, editor
