Sakki: feeling of deadly intent

Hiden no kata represents the very high level of Togakure ryu teaching. It is very difficult for understanding, because the understanding of Sakki jutsu ('the feeling of killing intention', 'the sixth sense feeling') is necessary for grasping and understanding the Hiden no kata. This level of Ninjutsu warrior skill becomes understandable and attainable for the practitioners only after the decades of proper training, learning and understanding.

Bottom line: "
after the decades of proper training!" :)
