Longnü


Longnü, translated as Dragon Girl, along with Sudhana are considered acolytes of the bodhisattva Avalokiteśvara in Chinese Buddhism. However, there are no scriptural sources connecting both Sudhana and Longnü to Avalokiteśvara at the same time. It is suggested that the acolytes are representations of the two major Mahāyāna texts, the Lotus Sūtra and the Avataṃsaka Sūtra, in which Longnü and Sudhana appear, respectively.
The depiction of Longnü and Sudhana with Avalokiteśvara may have been influenced by the Jade Maiden and Golden Youth who both appear in the iconography of the Jade Emperor. She is described as being the eight-year-old daughter of the Dragon King of the East Sea.

In the Lotus Sūtra

Longnü is depicted in the 12th Chapter of the Lotus Sūtra as being full of wisdom and achieving instant enlightenment. In the Lotus Sūtra, Mañjuśrī Bodhisattva speaks of her, saying:
There is the daughter of the nāga king Sāgara who is only eight years old. She is wise; her faculties are sharp; and she also well knows all the faculties and deeds of sentient beings. She has attained the power of recollection. She preserves all the profound secret treasures of the Buddhas, enters deep in meditation, and is well capable of discerning all dharmas. She instantly produced the thought of enlightenment and has attained the stage of nonretrogression. She has unhindered eloquence and thinks of sentient beings with as much compassion as if they were her own children. Her virtues are perfect. Her thoughts and explanations are subtle and extensive, merciful, and compassionate. She has a harmonious mind and has attained enlightenment.

However, the Buddha's disciple Śāriputra, a Sravaka, does not believe that a woman can attain buddhahood. In response, the nāga maiden offers a pearl to the Buddha, symbolizing her life and ego, and he accepts it. She then instantly transforms into a perfected male bodhisattva, and then attains complete enlightenment.
According to Schuster, the Lotus Sutra´s argument "is directed against the notion that some bodies are fit for the highest destinies, and other bodies are not."
In Chan Buddhism, the story was taken as an example to emphasize the potential of sudden awakening.

In folk tales

Tale of the Southern Seas

A single chapter in the Complete Tale of Avalokiteśvara and the Southern Seas, a sixteenth century Ming Dynasty novel is the first text that connects Longnü and Sudhana together as being acolytes of Avalokiteśvara. When the Dragon King's third son was out for swim in the sea in the form of a carp, he was captured by a fisherman. Unable to transform into his dragon form due to being trapped on land, he was going to be sold and butchered at the local market. Once Avalokiteśvara learned of his predicament, she gave Shancai all her money and sent him to buy him from the market and set him free. Because the carp was still alive hours after it was caught, this drew a large crowd and soon a bidding war started due to people believing that eating this fish would grant them immortality. Shancai was easily outbid and begged the fish seller to spare the life of the fish, but to no avail and earning the scorn of the people at the market. It was then that Avalokiteśvara projected her voice from far away saying, "A life should definitely belong to one who tries to save it, not one who tries to take it". The crowd realizing their mistake soon dispersed and Shancai was able to bring the carp back to Avalokiteśvara and return it to the sea.
As a token of gratitude, the Dragon King asked Ao Guang to bring the "Pearl of Light", but his granddaughter volunteers to go in his father's place instead. After offering the pearl to Avalokiteśvara, she decides to stay with her and become her disciple to learn the Buddhist Dharma.

The Precious Scrolls

Unlike the Complete Tale of Avalokiteśvara and the Southern Seas which only briefly mentions Longnü, the Precious Scroll of Sudhana and Longnü, an eighteenth-nineteenth century scroll consisting of 29, is completely devoted to the legend of Longnü and Sudhana and seems to have a Taoist origin. The text is set during the Qianfu period of the Tang Dynasty. One day when Sudhana is walking down a mountain path to visit his father he hears a voice crying out for help. Upon investigation, it turns out to be the voice of a snake trapped in a bottle for the last eighteen years. The snake begs Sudhana to release her, upon which she turn into her true form, that of a monster, and threatens to eat him. When Sudhana protests at the snake's behavior, she makes the argument that than ēn is repaid by a feud, and that is the way of the world. However, the snake agrees to submit the argument to three judges.
The first judge the argument is presented to is the human incarnation of the Golden Water Buffalo Star, who agrees with the snake, given its past experience with humans. The Buffalo Star relates how it never wanted to descend to earth but was pushed out of the gates of heaven by Kṣitigarbha who took pity on the toiling masses. Kṣitigarbha vowed that if the humans did not repay a favor with a favor, his eyes would fall out and drop to the ground. Because of the Buffalo Star's fall to earth, which was face first, it lost all of its upper front teeth. It suffered greatly at the hands of humans; after years of toiling for its master, it was butchered and eaten. Because of this, Kṣitigarbha's eyes did indeed fall out, and transformed into the snails that the buffaloes now trample on when it plows the fields.
The second judge they encounter is the Taoist priest Zhuangzi, who also agrees with the snake, citing an experience he had when he resurrected a skeleton who then immediately took Zhuangzi to court and accused him of stealing his money.
The last judge they meet is a young girl. The girl tells the snake that it can eat her as well, if the snake could show her how it was able to fit into the bottle which Sudhana had released it from. As soon as the snake worms itself back into the bottle, it is trapped. The girl then reveals herself to be Avalokiteśvara. When the snake begs for mercy, Avalokiteśvara tells it that in order to be saved, it must engage itself in religious exercises in the Grotto of the Sounds of the Flood on Mount Putuo.
Three years later, Sudhana formally becomes an acolyte of Avalokiteśvara along with the Filial Parrot. After the snake has submitted itself to seven years of austerity, it cleanses itself of its poison and produces a pearl. It then transforms into Longnü and becomes an acolyte of Avalokiteśvara.
