No-one’s mind automatically shuts up, and nor is that the goal of meditation in the first instance - IMO the goal is to realise you observe your thoughts, but you are not defined by them.
That you are not your mind, and its ceaseless chatter, any more than you are your emotions, or your body - you are the ruler of these vehicles.
Get thee here and get started:
Can you masturbate?
You do NOT have to reply to me!
But if you can, then presumably you can hold some kind of image in mind long enough to, er, get the job done.
