A Japanese expression meaning 'death lust'. Sakki is projected by all with ill intentions towards you (even though they may be acting towards an honourable goal). Samurai who had obtained a great level of spiritual development were supposed to be able to detect the presence of enemies by their sakki and as well as being able to suppress their own. Buddhist belief says that to strike a man he must first return your sakki with sakki or fear, one who does neither is said to have attained Mu.
