_(a) The Altar._—On such an occasion the great hall of the Law may be used for the ceremony. Quite often a special altar is erected in an enclosure near the monastery on a platform one foot high and twenty-five feet on each side, overspread by a tent of green cloth. In the center seats are arranged for the presiding monk and his assistants. On each of the four sides of the altar is placed an image of the Dragon King who is supposed to control the rain. If an image is not obtainable a piece of paper inscribed with the name of the dragon may be used. Flowers, fruits and incense are spread before the images. On the doors of the tent are painted dragons with clouds. The tent and altar are green and the monks wear green garments, because green belongs to the spring and suggests rain. For this ceremony the monks prepare themselves by abstinence and cleansing. The presiding monk is one of high moral character and religious fervor. While some monks recite appropriate sutras, two others look after the offerings, the incense, and the sprinkling of water during the ceremony to suggest the coming of rain. The services continue day and night, being conducted by groups of monks in succession. _(b) The Prayer Service._—The ceremonial is opened by a chant as follows: “Pearly dew of the jade heavens, golden waves of Buddha’s ocean, scatter the lotus flowers on a thousand thousand worlds of suffering, that the heart of mercy may wash away great calamity, that a drop may become a flood, that a drop may purify mountains and rivers. “We put our trust in the Bodhisattvas and Mahâsattvas that purify the earth.” The chant ended, a monk takes a bowl of water and repeats thrice: “We put our trust in the great merciful Kuan Yin Bodhisattva.” Then follows the chant: “The Bodhisattva’s sweet dew of the willow is able to make one drop spread over the ten directions. It washes away the rank odors and dirt. It keeps the altars clean and pure. The mysterious words of the doctrine will be reverently repeated.” This chant ended, the monks intone incantations of Kuan Yin, quite unintelligible even to them, but of magical value. While these are being uttered, the presiding monk and his attendants walk around the altar, while one of them with a branch sprinkles water on the floor. This symbolizes the cleansing of the altar and of the monks from all impurities which might render the ritual ineffective. When the perambulating monks have returned to their place, while the sprinkler continues his duties, the monks repeat the words: “We put our trust in the sweet dew kings, Bodhisattvas and Mahâsattvas.” The Bodhisattvas have now come to the purified altar and while the abbot offers incense to them, the monks repeat the words:
