Use cup, bowl or incense burner deep enough to fill with earth or sand. Light charcoal on bottom edge until coal begins to ignite, sit charcoal on earth or sand within burner. Let sit for a brief period; until the coal has started to glow, then place resins or powder on charcoal. These coals will burn for an hour or so. Continue to place resins or powder on charcoal as they burn out and smoke decreases for a continuous burning. Once charcoal is lit, it should burn out thoroughly for the full period of time; it can not be extinguished and re-lit at another time.

"Break off a piece of dhoop coal, and hold with one hand while lighting the opposite corner until it flames.  Allow the coal to flame until a portion is hot enough to smolder.  A steady stream of smoke will rise.  Place the coal in a fireproof urn, censor, or on top of a pot of sand.  Place a portion of frankincense or other ingredients on top of the coal.  Both will slowly smolder.  Caution:  Keep burning coals away from children and animals.  Do not leave unattended."
