In kendo, we are taught to avoid the shikai — the four sicknesses of surprise (kyo), fear (ku), doubt (gi), and confusion (waku). These mental states cloud our judgment, weaken our resolve, and prevent us from seeing opportunities clearly. While they are often discussed in the context of combat, their influence extends far beyond the dojo.

When we are surprised, we lose composure and fail to respond with intention. In life, this happens when we face the unexpected — a sudden setback, an unfamiliar challenge — and panic before we adapt.

Fear keeps us from moving forward. In kendo, it stops the body from striking; in life, it stops the heart from trying. Fear of failure, embarrassment, or rejection paralyzes us more effectively than any opponent ever could.

Doubt erodes confidence. When we question our decisions or skills mid-action, our strike loses conviction. In life, self-doubt breeds second-guessing and opportunities may slip away in the pause between thought and action.

Finally, hesitation is the moment our spirit stalls. It’s when we see the opening but fail to move. In kendo, that instant is all it takes to be struck. In life, hesitation can mean losing momentum, missing timing, or letting chances fade because of uncertainty.

Overcoming shikai is not about suppressing emotion, but about understanding and managing it. Whether in the dojo or in everyday life, awareness and presence are the keys to clarity. A calm mind sees truth; a disturbed mind sees only noise
