First ensured
His own
Invulnerability;
Then he waited for
The enemy’s
Vulnerability.
Invulnerability rests
With self;
Vulnerability,
With the enemy.
The Skilful Warrior
Can achieve
His own
Invulnerability;
But he can never bring about
The enemy’s
Vulnerability.
Hence the saying
‘One can know
Victory
And yet not achieve it.’
Invulnerability is
Defence;
Vulnerability is
Attack.
Defence implies
Lack;
Attack implies
Abundance.
