Can we know more about the dragon pearls pls? I think you or Monkey Ruler mentioned that they're like a dragon's heart and that they're incredibly important. Could they be given to others? How special are they?
Clarification: the "they are like a dragon's heart/yaoguai's neidan" part is pretty much just a HC, though you see the same thing in modern works sometimes.
They are still incredibly important to dragons, though.
The first reference to a dragon pearl appeared in the Outer Chapters of Zhuangzi, and here's the translated excerpt from Ctext:
There was a man who, having had an interview with the king of Song, and been presented by him with ten carriages, showed them boastfully to Zhuangzi, as if the latter had been a boy. Zhuangzi said to him, 'Near the He there was a poor man who supported his family by weaving rushes (to form screens). His son, when diving in a deep pool, found a pearl worth a thousand ounces of silver. The father said, "Bring a stone, and break it in pieces. A pearl of this value must have been in a pool nine Zhong deep, and under the chin of the Black Dragon. That you were able to get it must have been owing to your finding him asleep. Let him awake, and the consequences to you will not be small!" Now the kingdom of Song is deeper than any pool of nine Zhong, and its king is fiercer than the Black Dragon. That you were able to get the chariots must have been owing to your finding him asleep. Let him awake, and you will be ground to powder.'
In the translated Buddhist scripture Commentary on the Great Perfection of Wisdom, the Mani Pearl is also said to be contained inside the brain of dragon kings, and those who possess the pearl are immune to poison and fire.
The belief that dragon pearls are either under the jaws or inside the mouths of dragons are still more common, tho.
There's also the famous Buddhist where the 8-years-old dragon/Naga girl, daughter of the dragon king Sagara, presents a precious pearl to the Buddha, instantly transforms into a man, and attains Buddha-hood.
Though in this case, the pearl is never said to be her own dragon pearl and probably just a treasure in her possession.
In the folklore compendium Shuyi Ji, dragon pearls are listed alongside "snake pearls", both of which can be spat out by their respective animals.
However, in the Yue region, a thousand snake pearls can't measure up to one "Rose Pearl" in worth, while a dragon pearl is more valuable than a thousand Mu of orange trees.
(This passage is likely copied directly from a Tang text called 灌畦暇语.)
Also, in the Tang-Song period, the "dragons playing with pearls" first shows up as a motif on bronze mirrors, before becoming an incredibly popular decorative pattern in the Ming & Qing.
As the above passages have shown, dragon pearls can clearly be taken away, and are 1) valuable in a monetary sense, and 2) can have magical effects.
