柳生新陰流
The word is rooted in Zen philosophy, and was chosen to describe a fundamental concept of the style. "Shingan" means "mind’s eye," or "heart's eye," and refers to the ability to sense or read an opponent's intentions via an inner sense. Originally called simply Shingan-ryū, it was later renamed Yagyū Shingan-ryū, due to the influence of Yagyu Tajima no Kami Munenori's Yagyū Shinkage-ryū.
