I realize that I already replied to this once, but I wanted to make another response not directly related to my other one, and it seemed too lengthly to add as an edit. I apologize if this is frowned upon at HN.
In Soto Zen Buddhism, the point isn't necessarily to "quiet the mind," because that implies that the running rivers of thoughts somehow dry up and give rise to a silent stillness. This may be the goal of some forms of meditation, but it is not the interpretation of Zen.
Dogen Zenji preferred to use the term shikantaza, which means something like "nothing but to hit sit," or less literally, "just sitting." The understanding is that rejecting thoughts is the other side of the coin of embracing thoughts: both are rooted in attachment to the thought, identification of the thought with the illusion of self or ego.
The "purpose" of shikantaza, also known as zazen (sitting meditation), is to neither accept nor reject thoughts. Thus the mind isn't necessarily becoming "quiet," but rather the process of self-aggrandizement is discontinued.
It might seem like I'm nitpicking over your word choice, but Zen in particular is a school that is very focused on how language itself is rooted in the concept of "I" and our ego. You can contrast shikantaza to other forms of meditation that utilize a particular focus, such as an image, which is something that Zen would not generally endorse (for you would simply be displacing grasping at one thing with another thing).
Shikantaza is tied to "thusness," or being fully in the moment, which webwanderings above explains quite well.
