Only the spirit is pure.
The mind may be swayed, the body may fail.
Only the soul cradles vengeance purely.
Become the weapon of the soul.

Where the mind hesitates, overcome it.
Where the body fails, replace it.
Aspire to the condition of the Primarch.
Emulate his union with steel.

Never waver.
Never retreat.
Never doubt.

The flesh is weak.
The weak shall be purged.
What remains is strength.
