From the time you begin to breathe, a war rages within.
From the time you attain citizenship of this world, you must struggle with your own frailties to stand upright, as a human being was meant to stand.
From the time you yearn to reach higher, you must engage the animal that comes dressed within this meat and bones, to carry it up with you. You must play its own game on its own turf, speak to it in its own language, meditate upon those matters that can inspire it, bear with it until you can bring it to the side of peace.
You must descend to a place of chaos and madness to redeem yourself from there.
And so this battle plays out not only in the spiritual arena of meditation and prayer, but also in the very human world of eating your meal, of raising a family, of worldly pursuits, infiltrating that world so as to conquer it, to rip away its veil and reveal the Godly sparks it contains, as Jacob dressed in the clothes of Esau, wrestling with his angel on the cold, sodden earth of a night to which he does not belong.
Yet at all times and in every situation you retain access to a point of perfect oneness within, a place where there is no opposition to fight, no choices that could be made, no existence at all, nothing other than “the Creator of all things to whom I am bound as one.”
It is not the battle that defines you, nor the role in which you must invest yourself, nor the opponent with whom you fight. You are none of these. You are that point of peace within.
And so, even your battle is in peace. [Lubavitcher Rebbe]
