In ancient times, the number of flowers, joss sticks and small candles presented to a temple was usually equal to the number of monks in that temple. Where there were surplus candles, villagers tended to make numerous small candles into large one for presenting to temples. The large candles being stronger, with more light and longer lasting.
Buddhists believe that offering candles to monks as a means of light will also brighten up their future. These candles are known as Thian Phansa.
