TDuring the three-month annul “rain retreat,” monks study more and teach those who have chosen this period to enter monkhood. Laymen usually visit temples to offer monks food, clothing, medicine, flower, joss sticks, Lenten candles and other offerings. Such practices they consider highly meritorious.
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.
