Ki-energy: invisible psychophysical energy

This article briefly introduces the phenomena of ki-energy to the Western
readers who are not familiar with them, by relying on Yuasa Yasuo's conceptual
scheme. Ki-energy has traditionally been an intense thematic focus of various
East-Asian fields of human endeavours such as acupuncture medicine, martial
arts and meditational training. The article articulates some of the salient
features of this energy as it is understood in these fields, while incorporating
knowledge of contemporary scientific research on them. It is written with
a view to stimulating further research on it, as it carries important implications
for addressing many of the issues we face today.
