The Lantern Show
All things have a purpose under Heaven.
All things.
The wise man. The nurse. The torturer. The demon. The maggot. The vampire.
All things have a purpose. Most are wise enough to know what that purpose is. Kuei-jin, however, must learn their place under Heaven before they can assume the true powers of their office. More to the point, they must understand what they are before they can come to terms with their undead state. By all measures, the Kuei-jin are unclean parasites, shut off from the sight of all good folk. They may be powerful, even immortal, but that power grows thin when compared to the endless hunger og eternal nights.
Face with this emptiness, the Grand Arhat Xue despaired. As the Wan Xian scattered, Xue wandered off on a long journey. He searched for 1,000 years, ad he asked secrets of the five elements as he searched. In time, he assembled a Fivefold Way, and founded, it is said, five Dharmas: diving philosophies to guide the footsteps of the Damned.
Creation may indeed be a shadowplay, but it a show with substance. Like the flickering images thrown by a lantern (which, as many mystics believe, have lives of their own), the illusions of the mortal world grant insight into the greater truths. By discovering his place in that shadowplay, a Kuei0jin finds purpose; by transcending that place and the world around it, he (theoretically) finds peace.
Despite their name -- a corruption melding Xue's term Di'hana with the Sanskrit term for destiny's law -- Dharmas are not Hindu, not Buddhist, not Confucian, Taoist, Shinto or even Christian. They are elemental paths, the trails of which were blazed long before the philosophers and prophets of the great religions were born. Not to say that Kuei-jin concepts haven't been influenced by the grand cultural sweeps of Buddhism and the other faiths; the modern name attests to that much. However, Cathayans who would see true enlightenment must, as always, go beyong the easy roads imposed by mortal vision and seek the traces of faint footprints and snapped twigs, the traces that reveal the path of the true visionary.
It's also vital to remember that Kuei-jin are monsters. Vampires. Eaters of life-force. Animated corpses. And they are very much aware of that fact. The Dharmas can be seen as avenues to transcendence, but many Cathayans regard them as roads to perfection instead. If one is a monster, then it stands to reason that perfection often means becoming more of a monster than one already is. Hence, Kuei-jin are not "Grasshopper" - spouting sages, peacefully picking lotus flowers in search of enlightenment; they are monsters seeking a purpose to their unlives.
A Dharma is not a path to power or a roadmap of enlightenment; consider it, instead, to be a series of auspicious stones, a trail of bent grass-blades markings the way of ones who went before. Each vampire must find her own path; a Dharma merely tells a vampire where to start looking, not where to find each and every step. The search is part of the larger journey.
