Why Goku defeated Ten Shin Han

When Ten Shin Han used his technique to split into four copies, it looked impressive — four warriors instead of one. But Goku, calm and focused, recognized the weakness in that move instantly.
Goku told him:
“That was your biggest mistake.”
Why? Because Ten didn’t multiply his power — he split it. Each copy was only one-fourth of his original strength. He looked more powerful, but he was actually weaker.
Focus is power. When we scatter, we weaken. But with full presence, we gain strength. The undivided mind wins.
