Students may indeed be encouraged to practice Taoist Yoga exercises or tai chi as a way of building enough energy to begin performing the microcosmic orbit exercise as it can induce a strain on the nervous system and ...
Completeness is a property of the metric and not of the topology, meaning that a complete metric space can be homeomorphic to a non-complete one. An example is given by the real numbers, which are complete but homeomorphic to the open interval (0,1) , which is not complete.
In mathematics, the least-upper-bound property (sometimes called completeness, supremum property or l.u.b. property) [1] is a fundamental property of the real numbers. More generally, a partially ordered set X has the least-upper-bound property if every non-empty subset of X with an upper bound has a least upper bound (supremum) in X .
Semantic completeness is the converse of soundness for formal systems. A formal system is complete with respect to tautologousness or "semantically complete" when all its tautologies are theorems, whereas a formal system is "sound" when all theorems are tautologies (that is, they are semantically valid formulas: formulas that are true under every interpretation of the language of the system ...

All completeness properties are described along a similar scheme: one describes a certain class of subsets of a partially ordered set that are required to have a supremum or required to have an infimum. Hence every completeness property has its dual, obtained by inverting the order-dependent definitions in the given statement. Some of the ...
This form tends to emphasize manipulation, seizing and grappling and a tight method of spiral winding for both long and shorter range striking. Zhu Tian Cai has commented that the Xinjia emphasizes the silk reeling movements to help beginners more easily learn the internal principles in form and to make application more obvious in relation to ...
Many systems of qigong practice include the use of external agents such as ingestion of herbs, massage, physical manipulation, or interaction with other living organisms. [14] For example, specialized food and drinks are used in some medical and Daoist forms, whereas massage and body manipulation are sometimes used in martial arts forms.
