Should we use agarbattī or dhūpa? Is it wrong to burn bamboo incense sticks?
dhūpa is the older offering and many prefer bambooless cones or sticks; use whichever is natural, and keep the room ventilated.
Dhūpa, fragrant smoke, is one of the five basic offerings (pañcopacāra) along with sandal paste, flowers, lamp and food. Traditionally it was made from resins like guggul and loban, herbs, and ghee, burned on coal or as cones. Agarbattī — incense on a bamboo stick — is a later and very popular form.
You will often hear that burning bamboo is inauspicious. This is a widespread belief, linked partly to bamboo being used in funeral rites, and many families therefore choose dhūpa cones, dhūpa sticks without bamboo, or sāmbrāṇī. Others use agarbattī without concern. Neither is a matter of sin; choose according to your family’s custom.
More important is quality and health: prefer natural ingredients over synthetic perfumes, use small amounts, keep a window open, and be careful around children, the elderly and anyone with asthma. A little fragrance offered with attention is enough.
