What not to do
Never use kerosene, petrol or spirit to start or revive the fire — camphor and dry wood are enough. Don't offer plastic, synthetic items, or packaged food in wrappers. Don't blow on the fire with your mouth; tradition prefers a hand-fan, and it is also safer.
Don't leave the fire unattended. Let the ashes cool completely — usually several hours — before handling. The cooled ash can go into the garden or a plant pot, or be immersed respectfully.
