WaidanWaidan, translated as 'external alchemy' or 'external elixir', is the early branch of Chinese alchemy that focuses upon compounding elixirs of immortality by heating minerals, metals, and other natural substances in a luted crucible. The later branch of esoteric neidan 'inner alchemy', which borrowed doctrines and vocabulary from exoteric waidan, is based on allegorically producing elixirs within the endocrine or hormonal system of the practitioner's body, through Daoist meditation, diet, and physiological practices.
Cantong qiThe Cantong qi is deemed to be the earliest book on alchemy in China. The title has been variously translated as Kinship of the Three, Akinness of the Three, Triplex Unity, The Seal of the Unity of the Three, and in several other ways. The full title of the text is Zhouyi cantong qi, which can be translated as, for example, The Kinship of the Three, in Accordance with the Book of Changes. According to the traditional view, well-established in China, the text was composed by Wei Boyang in the mid-second century CE, and deals entirely with alchemy—in particular, with Neidan, or Internal Alchemy.
Elixir of lifeThe elixir of life, also known as elixir of immortality, is a potion that supposedly grants the drinker eternal life and/or eternal youth. This elixir was also said to cure all diseases. Alchemists in various ages and cultures sought the means of formulating the elixir. An early mention of an elixir of life is found in the Epic of Gilgamesh (from the 2nd millennium BC) in which Gilgamesh comes to fear his own declining years following the death of his beloved companion Enkidu.
Chinese theologyChinese theology, which comes in different interpretations according to the classic texts and the common religion, and specifically Confucian, Taoist, and other philosophical formulations, is fundamentally monistic, that is to say it sees the world and the gods of its phenomena as an organic whole, or cosmos, which continuously emerges from a simple principle. This is expressed by the concept that "all things have one and the same principle" (wànwù yīlǐ 萬物一理).
Chinese alchemyChinese alchemy is an ancient Chinese scientific and technological approach to alchemy, a part of the larger tradition of Taoist body-spirit cultivation developed from the traditional Chinese understanding of medicine and the body. According to original texts such as the Cantong qi, the body is understood as the focus of cosmological processes summarized in the five agents of change, or Wuxing, the observation and cultivation of which leads the practitioner into alignment and harmony with the Tao.
Chinese alchemical elixir poisoningIn Chinese alchemy, elixir poisoning refers to the toxic effects from elixirs of immortality that contained metals and minerals such as mercury and arsenic. The official Twenty-Four Histories record numerous Chinese emperors, nobles, and officials who died from taking elixirs to prolong their lifespans. The first emperor to die from elixir poisoning was likely Qin Shi Huang (d. 210 BCE) and the last was the Yongzheng Emperor (d. 1735 CE).
NeidanNeidan, or internal alchemy (), is an array of esoteric doctrines and physical, mental, and spiritual practices that Taoist initiates use to prolong life and create an immortal spiritual body that would survive after death. Also known as Jindan (金丹 "golden elixir"), inner alchemy combines theories derived from external alchemy (waidan 外丹), correlative cosmology (including the Five Phases), the emblems of the Yijing, and medical theory, with techniques of Taoist meditation, daoyin gymnastics, and sexual hygiene.
Religion in ChinaThe People's Republic of China is officially an atheist state, but the government formally recognizes five religions: Buddhism, Taoism, Christianity (Catholicism and Protestantism are recognized separately), and Islam. In the early 21st century, there has been increasing official recognition of Confucianism and Chinese folk religion as part of China's cultural heritage. Chinese civilization has historically long been a cradle and host to a variety of the most enduring religio-philosophical traditions of the world.
TaoismTaoism or Daoism (ˈtaʊɪzm̩ or ˈdaʊɪzəm) refers to a Chinese philosophy, or a set of Chinese traditions and religions that emphasize living in harmony with the Tao (, 'Path'). The Tao is generally defined as the source of everything and the ultimate principle underlying reality. The Tao Te Ching and the Zhuangzi are widely considered key Taoist texts and are distinctly philosophical in nature and theme. Taoism includes various self-cultivation methods, including meditation, internal alchemy, and various rituals.
