The burned incense serves as an aid in prayer. The censer or burner is one of the most significant items in the Liturgy since the smoke of burning incense is interpreted by both the Western Catholic and Eastern Christian churches as a symbol of the prayer of the faithful rising to heaven. The censer may be with chains or a hand censer.
