Ignite a dhoop charcoal (specially made for incense burning) by using the flame of a stove or candle. The briquette should start to crackle and glow.
Next, set the charcoal in a container on a bed of sand. You can also use a dhoopdan for lighting the dhoop. The sand layer under the charcoal should be at least 3/4-1 inch thick.
Slowly fan or blow on the tablet. Only after the charcoal is aglow and stops crackling, use a knife, spoon or tweezers to drop the incense onto the tablet. Fan the dhoop to let the aroma spread.
Lastly, charcoal may continue to burn for two hours after lighting - so don't just throw it in a wastebasket. Use tweezers to extract the tablet and submerse it in water to discard if the tablet is still lit.
