Miyamoto Musashi Quote

The spirit of the smacking parry is not parrying, or smacking strongly, but smacking the enemy's long sword in accordance with his attacking cut, primarily intent on quickly cutting him. If you understand the timing of smacking, however hard your long swords clash together, your swordpoint will not be knocked back even a little. You must research sufficiently to realise this.
