A broad mind lacks focus.
A questioning servant is more dangerous than an ignorant heretic
A small mind is easily filled with faith.
A warrior's faith in his commander is his best armour and his strongest weapon.
Adamantium walls and plasteel bulkheads may seem formidable, but an unshakable faith in the Immortal Emperor of Man can overcome any barriers.
An Empty Mind Is A Loyal Mind
An open mind is like a fortress with its gate unbarred and unguarded.
Better crippled in body than corrupt in mind.
Consider the Predator. Let your soul be armoured with Faith, driven on the tracks of Obedience which overcome all obstacles, and armed with the three great guns of Zeal, Duty and Purity.
Facts are chains that bind perception and fetter truth. For a man can remake the world if he has a dream and no facts to cloud his mind.
Faith without deeds is worthless.
Happiness is a delusion of the weak
Forgiveness is a sign of weakness.
He who lives for nothing is nothing. He who dies for the Emperor is a hero.
If a man dies that another should live, that man's spirit shall eat at the Emperor's table
Innocence proves nothing
It is better to die for the Emperor than to live for yourself.
Leniency is a sign of weakness!
Mercy is a sign of weakness.
No man that died in the Emperor's service died in vain.
Nobody is innocent, there are merely varying levels of guilt.
Only in death does duty end.
Only the insane have strength enough to prosper. Only those who prosper may truly judge what is sane.
Pain is an illusion of the senses, despair an illusion of the mind
Purge those who are unclean.
Sometimes the good must perish so that the rest survive. The lot of courage is to be sacrificed upon the altar of battle.
Survival is no birthright, but a prize wrested from an uncaring galaxy by forgotten heroes.
The common man is like a worm in the gut of a corpse, trapped inside a prison of cold flesh, helpless and uncaring, unaware even of the inevitability of its own doom.
The Emperor will not judge you by your medals and diplomas but by your scars.
Though silver in your palms weighs light
Compared to death by blast and sword,
Do not shy the hopeless fight,
For endeavour is its own reward.
