The body knows what to do to survive.
The mind is much slower than the body’s instincts and the mind makes a lot of mistakes.
It’s not good if the mind overrides the instinct.
However, you need the mind to defend, because instincts knows just to survive.
Therefore, the instinct* is leading the movement, use the mind to modify the instinct, according to the situation**.
* Bruce Lee said: ‘Empty your mind’.
** it maybe necessary to strike, it maybe necessary just to control somebody, it maybe a mistake & you need to mask it for another movement. 😉
