In the Sufi practice of adab, objects are seen as manifestations of the Beloved and so in humility and gratitude dervishes kiss the tea glass from which they drink or the carpet on which they have just prayed.
According to Sheikh Kabir Helminski, a dervish doesn't "put out" a candle, s/he "puts it to rest."
How can it feel to demonstrate respect and love for your cherished things?
