Budo Taijutsu, is like a bear waking from a long hibernation.

"Budo Taijutsu, which is by no means exclusively Japanese, is like a bear waking from a long hibernation. And now humankind is starting to wake up. The reason I draw the analogy of the hibernating bear is because regarding Taijutsu, the essence of fighting, mankind has been sleeping and has forgotten this essence. Martial friends, the alarm bell has started ringing. Wake up from your slumber!" - Masaaki Hatsumi

Gokui

"My belief is that gokui, or essence, is living with change (henka). If people change then things change and the times change. It would be strange, therefore, if each respective era didn't have gokui. Ironically, gokui is about change; people and times must change, but the fundamental aspect of gokui does not change. Budo has existed for thousands of years and the fact that my Budo is understood around the world shows that it exists within something that is like the gokui." - Masaaki Hatsumi
