Quan Yin is a shortened form of a name that means One Who Sees and Hears the Cry from the Human World. Her Chinese title signifies, "She who always observes or pays attention to sounds," i.e., she who hears prayers. Sometimes possessing eleven heads, she is surnamed Sung-Tzu-Niang-Niang, "lady who brings children." She is goddess of fecundity as well as of mercy. Worshipped especially by women, this goddess comforts the troubled, the sick, the lost, the senile and the unfortunate. Her popularity has grown such through the centuries that she is now also regarded as the protector of seafarers, farmers and travelers. She cares for souls in the underworld, and is invoked during post-burial rituals to free the soul of the deceased from the torments of purgatory. There are temples all over China dedicated to this goddess, and she is worshipped by women in South China more than in the North, on the 19th day of the 2nd, 6th and 9th moons. (For example, it is a prevalent birth custom in Foochow that when a family has a daughter married since the 15th day of the previous year, who has not yet given birth to a male infant, a present of several articles is sent to her by her relatives on a lucky day between the 5th and 14th of the first month. The articles sent are as follows: a paper lantern bearing a picture of the Goddess of Mercy, Quan Yin, with a child in her arms, and the inscription, "May Quan Yin present you with a son"; oysters in an earthenware vessel; rice-cakes; oranges; and garlic.) Worshippers ask for sons, wealth, and protection. She can bring children (generally sons, but if the mother asks for a daughter she will be beautiful), protect in sorrow, guide seamen and fishermen (thus we see her "crossing the waves" in many poses), and render harmless the spears of an enemy in battle. Her principal temple on the island of Putuoshan, in the Chusan Archipelago off the Zhejiang coast near Ningbo, is a major pilgrimage site sacred to the Buddhists, the worship of Quan Yin being its most prominent feature on account of the fact that the Goddess is said to have resided there for nine years, reigning as the Queen of the Southern Seas. The full name of the island is P'u t'o lo ka, from Mount Pataloka, whence the Goddess, in her transformation as Avalokiteshvara, looks down upon mankind. Miao Feng Shan (Mount of the Wondrous Peak) attracts large numbers of pilgrims, who use rattles and fireworks to emphasize their prayers and attract her attention. In 847, the first temple of Quan Yin was built on this island. By 1702, P'u Tuo had four hundred temples and three thousand monks, and was the destination of countless pilgrims. (By 1949, however, P'u Tuo was home to only 140 monasteries and temples.)
No other figure in the Chinese pantheon appears in a greater variety of images, of which there are said to be thousands of different incarnations or manifestations. Quan Yin is usually depicted as a barefoot, gracious woman dressed in beautiful, white flowing robes, with a white hood gracefully draped over the top of the head and carrying a small upturned vase of holy dew. (However, in the Lamaistic form, common in bronze from eighteenth-century China and Tibet, she is often entirely naked.) She stands tall and slender, a figure of infinite grace, her gently composed features conveying the sublime selflessness and compassion that have made her the favorite of all deities. She may be seated on an elephant, standing on a fish, nursing a baby, holding a basket, having six arms or a thousand, and one head or eight, one atop the next, and four, eighteen, or forty hands, which which she strives to alleviate the sufferings of the unhappy. She is frequently depicted as riding a mythological animal known as the Hou, which somewhat resembles a Buddhist lion, and symbolises the divine supremacy exercised by Quan Yin over the forces of nature. Her bare feet are the consistent quality. On public altars, Quan Yin is frequently flanked by two acolytes, to her right a barefoot, shirtless youth with his hands clasped in prayer known as Shan-ts'ai (Golden Youth), and on her left a maid demurely holding her hands together inside her sleeves known as Lung-nü (Jade Maiden). Her principal feast occurs yearly on the nineteenth day of the second lunar month. However, she is fortunate in having three birthdays, the nineteenth of the second, sixth and ninth months. There are many metamorphoses of this goddess. She is the model of Chinese beauty, and to say a lady or a little girl is a Kwan Yin is the highest compliment that can be paid to grace and loveliness.
According to one ancient legend her name was Miao Shan, and she was the daughter of an Indian Prince. Youthful and serene, she chose to follow a path of self-sacrifice and virtue, and became a pious follower of Buddha, herself attaining the right to budddhahood but remaining on earth to help mankind. In order to convert her blind father, she visited him transfigured as a stranger, and informed him that were he to swallow an eyeball of one of his children, his sight would be restored. His children would not consent to the necessary sacrifice, whereupon the future goddess created an eye which her parent swallowed and he regained his sight. She then persuaded her father to join the Buddhist priesthood by pointing out the folly and vanity of a world in which children would not even sacrifice an eye for the sake of a parent.
Another Miao Shan legend was that the son of the dragon king had taken the form of a carp and was caught by a fisherman and displayed for sale in the market place. Miao Shan sent her servant to buy the fish and released it.
As related in yet another legend Quan Yin was said to be the daughter of a sovereign of the Chou dynasty, who strenously opposed her wish to be a nun, and was so irritated by her refusal to marry that he put her to humiliating tasks in the convent. This means of coercion failed, and her father then ordered her to be executed for disobedience to his wishes. But the executioner, a man of tender heart and some forethought, brought it about that the sword which was to descend upon her should break into a thousand pieces. Her father thereupon ordered her to be stifled. As the story goes, she forthwith went to Hell, but on her arrival the flames were quenched and flowers burst into bloom. Yama, the presiding officer, looked on in dismay at what seemed to be the summary abolition of his post, and in order to keep his position he sent her back to life again. Carried in the fragrant heart of a lotus flower she went to the island of Putuo, near Ningbo. One day her father fell ill and according to a Chinese custom, she cut the flesh from her arms that it might be made into medicine. A cure was effected, and in his gratitude her father ordered her statue to be made "with completely-formed arms and eyes." Owing to a misunderstanding of the orders the sculptor carved the statue with many heads and many arms, and so it remains to this day.
The image of this divinity is generally placed on a special altar at the back of the great Shakyamuni Buddha behind a screen, and facing the north door, in the second half of the Buddhist monastery. Quan Yin is also worshipped by the Taoists, and they imitate the Buddhists in their descriptions of this deity, speaking in the same manner of her various metamorphoses, her disposition to save the lost, her purity, wisdom, and marvel-working power.
From early Ch'ing times to the present, many thousands of statues of Quan Yin have been carved in jade. The Maternal Goddess, the Protectress of Children, the Observer of All Sounds, Quan Yin is a favorite figure in domestic shrines. As well, her image is carved on small jades which Chinese women offer faithfully at the temples dedicated to her. She also is the single most important figure crafted in blanc de Chine ware, with approximately nine out of every ten figures from Dehua representing that divinity in one or other of her manifestations. (The Quan Yins often were described to European purchasers as "white Santa Marias," so as to make them more desirable to a Christian market.)
