How to prepare for the unknown? (I assume you mean something which is known, but the effects of which are not.)

First I try prayer, and in meditation I try to recall some similar event in history. Second I consider the similarities and differences to my current situation, and try to come up with a few senarios which may occur. These two exersizes often provide me with some insight/preparation for a sequence of events.

Of course it doesn't always work. Sometimes life just hands you your head on a platter. For those times, (which are more reaction than preparation) I just try to remember that there are probably thousands of people who have it a lot worse. (Half of the world's population survives on only a few dollars a day.)

(Music is also helpful: Phil Collins Another Day in Paradise is a good example.)

A disturbance in the force I feel. A new Sith lord now asks to be President -- Lord McCain.
With his apprentice Palin, they draw strength from the essense of the dark side:
Anger, Fear,  Agression, Racism and Hatred.

As I have said:
 "Fear is the path to the dark side: fear leads to anger, anger leads to hate, hate leads to suffering. Suffering feeds the fear"

Is the dark side stronger? No, it is simply more seductive.

Lord McCain is a master of deception and illusion. Tries to hide behind the skirts of his apprentice does he, yet their true hues of darkness still shine through.

Beware of quick phases (sound-bytes), and simplifications. Beware the ideologies which hide behind them. Think, Ponder, Study and Vote!

Once asked, a wise person did:
"Who's the more foolish...the fool or the fool who follows him?" (Obi Wan Kenobi)

It sickens me to hear the fools Bush and Cheney speak of war with Iran. McCain sings about bombing, like its a game. These dolts are so isolated and warped that they believe their own lies. Fools they are.

But what of those whom are still supporting them?

Seems now as the election nears, logic and wisdom are not part of the equation, but rather ideologies. 

Where to go? Who to support? Hard to know this is.
Carefully I have pondered, and given the choices, Obama support as President I do. Reservations I still have, but my choice is clear.

-- Yoda, call me some.

Now clear it becomes who's darkness curses the land,
Darth Cheney named is he.
Above the law  he claims to be
Taken with the dark side, his hate burns for Iran.

Blinded by the darkness within his soul,
Endless war is his goal.

Something wicked this way comes
And now clear it becomes,
Wise to impeach him now it is.

More money for war asks Bush,
a clear message from voters there is,
Say No! They do.

Troops support them, cries Bush,
though true concern for them there is not.
Weary of such BS, our nation grows.

Troops support them we do.
For them we march, write, and yell.
Bring them home now, we must.

Money for war, we need no more.

Out of shame and sadness I write.

My heart troubled by US leaders it is. Ashamed of President am I.
Follows the Prince of Peace, he claims, yet sanctions violence does he.

Angry I am. Wrong for Israel to kill it is.
Wrong for USA for tools of death to provide.
Wrong for anyone to kill.
Understand this you must.

Sides in conflict, take you must not. Both sides have been wronged, see this I do.
But the force, room for hate it has not.

That is a path to the dark side.
Peace with diplomacy, end of hostilities does begin. Like a seed is it.

In keeping with my character, here is my version of the exchange in episode III:
[my comments/dialogue in square brackets]

The scene is Yoda speaking with the young jedi, who is disturbed
by the nightmares of loosing his wife. He tells the master Yoda
of his fears.
The wise Yoda responds:
    "Fear of loss is a path to the dark side. [Understand you must]
     Death is a natural part of life."
    "Rejoice for those around you who transform into the force."
    "Mourn them do not, miss them do not."
    [Love them you do, see this I can, good this is. Enjoy this
     now, for we know not what tomorrow will be.  But beware ]
    "Attachment leads to jealousy, the shadow of greed that is."

    "What must I do master?"

    "Train yourself to let go of everything to fear to loose."
    [Only then can you realize freedom from the forces of the dark side.]

This response is interesting because it shows him the path, but
knowing the path, and walking the path are quite different things. In the end
Anikin gives into his fears, only to find that in doing so his fears are realized.

Ghandi was asked just hours before his assasination if the non-violent
resistance to government would have worked with a more harsh, less
honorable foe than the Brits. His answer was affirmative, but that it would require the type of committment and sacrifice Yoda speaks of.

Those who are pushing for war in Iran (because of their fears) may find themselves
on a path similar to that of Anakin.

    Love thy Neighbor -- Preemptively

The folly of WAR becomes clearly apparent when one examines history, and listens to the calls of those who have experienced the reality of war, rather than the fantasies of those who have not.
