Children have important roles during Undas. Children are allowed to play with melted candles in front of grave sites and turn the melted wax from the candles into round wax balls. The round balls of wax symbolize the affirmation that everything goes back to where it began, as the living will go back to ash, where everything started. In some cases, families also light candles at the front door of the home. The number of candles is equivalent to the number of departed loved ones. It is believed that this tradition aids departed loved ones and provide them with a happy path to the afterlife.
