Incense gives that special whiff to worship; it is the smell of prayer and adoration.

We are told that we have stored within our brain a catalog of fifty thousand different smells. The smell of incense awakens the primitive memories of sacrifices and holocausts. . . . In the religions of the Western industrialized world, incense is an antique or an alien visitor from some exotic, Oriental religion. But we don't have to be a Zen disciple or a "super-orthodox traditionalist" to enjoy the pungent smell of incense or to use it as part of our prayer.
