question:  Why was the water important in this story?
context: Safe from the scrutiny of brothers and parents, there was nothing now to stop him from going to the ocean. It was exactly as he knew it would be: the milky-orange stream had become motionless and its minute whirlpools had stopped whirling; a nearby bee hung suspended over a paka plant, its transparent wings frozen in position for a downward stroke; and the heavy purple fluid overhead held fast in its manufacture of whorls and nimbi.
