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.
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.
Taoist meditationTaoist meditation (ˈdaʊɪst, ˈtaʊ-), also spelled Daoist (ˈdaʊ-), refers to the traditional meditative practices associated with the Chinese philosophy and religion of Taoism, including concentration, mindfulness, contemplation, and visualization. The earliest Chinese references to meditation date from the Warring States period (475–221 BCE). Traditional Chinese medicine and Chinese martial arts have adapted certain Daoist meditative techniques.
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.
Hun and poHun () and po () are types of souls in Chinese philosophy and traditional religion. Within this ancient soul dualism tradition, every living human has both a spiritual, ethereal, yang soul which leaves the body after death, and also a corporeal, substantive, yin soul which remains with the corpse of the deceased. Some controversy exists over the number of souls in a person; for instance, one of the traditions within Daoism proposes a soul structure of 三魂七魄; that is, "three and seven ".
DantianDantian, dan t'ian, dan tien or tan t'ien is loosely translated as "elixir field", "sea of qi", or simply "energy center". Dantian are the "qi focus flow centers", important focal points for meditative and exercise techniques such as qigong, martial arts such as t'ai chi ch'uan, and in traditional Chinese medicine. Historically the first detailed description of the lower Dantian is in the Laozi zhongjing 老子中經 from the 3rd century CE, which refers to the elixir-of-life field where "essence" and "spirit" are stored; it is related to regeneration and sexual energy, menstruation and semen.
