That's a concept I've been wrestling with over the past few months... and the conclusion I've come to thus far is this:
It's been said in many great teachings and especially in quantum physics that all possibilities exist side by side simontaneously. So that means, out there exists both a reality where you've chose option A as opposed to option B, and vice versa.
Now if someone else prior to your decision put out their own intentions for you to choose option B, there's already a reality in which you have. So they wouldn't necessarily be forcing you to choose one thing or another, because you've already chosen both. Make sense? They are simply choosing the reality in which they desire to experience, as are you. So no one is ever really being controlled by another. The only time we think we are is when we choose to be, and even then we're only controlling ourselves. It's one of those big paradoxes you're gonna start running into a lot of

. The deeper you go, the more pliable logic gets to the point where you have no use for it, and when it begins to fade like that we start to call it things like coincidences, and miracles, or even cooler words -- like magic
