setTimeout runs only once instead of repeatedly

Question

I want to make the div fadeIn and fadeOut after every 2 seconds, but the setTimeout function is running only once and hiding the div, but that is it. It is not doing it more than once:

HTML:

<a href="javascript:void(0);">Pyp1</a>
<div id="disable">
    Hello!
</div>

JavaScript (jQuery):

$(document).ready(function(){
    setTimeout(function() {
        $('#disable').toggle('fast');
    }, 2000);
});

Fiddle

However, when I write the same thing for the click event, it actually works:

$(document).ready(function(){
    $('a').click(function() {
        $('#disable').fadeToggle('fast')
    });
});

Fiddle

I've tried searching around (in Stack Overflow as well) and couldn't get the answer, I tried the click approach and it worked, but that is not the result I am looking for.

Where exactly is the problem and how may I fix it?

@dandavis Damn! Seriously forgot about that, sorry, will delete the question to maintain quality, but one more thing: I've heard that after sometime, it actually stops working, setinterval, is there an alternative? — Always Learning Forever, Aug 17 '14 at 15:18
you can call setTimeout from the bottom of the function setTimeout calls... — dandavis, Aug 17 '14 at 15:19
that was a bit unclear, may you provide an example, or something? — Always Learning Forever, Aug 17 '14 at 15:19
$(document).ready(function FN(){ setTimeout(function() { $('#disable').toggle('fast'); setTimeou(FN, 2000) }, 2000);}); — dandavis, Aug 17 '14 at 15:20
Also, please upvote my post as I am banned from asking any question(s), I can't live without Stackoverflow! Sorry... — Always Learning Forever, Aug 17 '14 at 15:21

This is because setTimeout runs only once, how can you expect it to run multiple times? Use setInterval instead.
