Qi

Qi (/tɕʰî/ or /ˈtʃiː/), or chi with the same pronunciations, is an metaphysical property in psionology and other philosophical and spiritual courses of study.

The following statements are true of all qi: However unlike energy, qi can not be measured, nor expressed in terms of mass or density.
 * 1) It can be transferred to other objects;
 * 2) It can be converted into other types of qi;
 * 3) It obeys the law of conservation of energy (it cannot be created or destroyed) despite not actually being energy.

Etymology
Qì 氣 was a Chinese logogram that was originally constructed as "steam (气) rising from rice (米) as it cooks." It was traditionally used to mean "air," "gas," "smell," or "breath," or in the verbal form "to breathe" or "to get angry." Around the fifth century BC, Chinese philosophers such as Kǒng Zǐ (Confucius) and Mòzǐ began to use the term to describe the life-process or flow of energy that sustains living beings.

Qi in psionology
There is some discrepancy as to whether psionology studies energy, qi, or both. Traditionally the term "energy" has been used for all demonstrated psionic phenomena (as opposed to independent phenomena), but in recent years there has been a growing push to use the term "qi" to clarify that the phenomena do not necessarily behave in a way that can be described by physics. The most commonly held theory of psionic phenomena is that a person can use their qi to affect their energy or the energy of their immediate environment, thus relating the two concepts without equating them.
