I'm highly fond of incense, when I see the smoke billow and spread out it's like an ethereal force pushing out the evil, kind of a holy fumigation. Then you have the smell, it amazes me that anyone can not like it, I love it. It's a welcoming and warming smell to me, it's a sign that something sacred is or has been going on. Another great aspect of the use of incense is the symbolism of rising prayers, seeing the smoke rise is a concrete reminder of our connection to God.
Dirigatur oratio mea sicut incensum in conspectu tuo,elevatio manuum mearum ut sacrificium vespertinum. - Psalm 141
