This is a beautiful passage from Paulo Coehlo. Thank you, kind sir.
The warrior of the light sometimes behaves like water, flowing around the many obstacles he encounters.
At certain times, resistance means to be destroyed. At such times, he adapts to circumstances. He accepts, without complaint, that the rocks along the way forge his path down the mountains.
Such is the force of water: it can never be broken by a hammer, or wounded by a knife. The most powerful sword in the world is incapable of leaving a scar on its surface.
The water of a river adapts to the path which is possible, without forgetting its objective: the sea. Fragile at its spring, it gradually acquires the strength of the other rivers it encounters.
And, after a while, its power is absolute.
