Yes, you attract the circumstances to bring about the 'result' of the vibration.

Often, what occurs will seem entirely unrelated to what you desire. But later on, looking back, you can see how all these things formed a chain to bring about the desire...and how valuable even the most odd and 'out of place' event was.

Contrary to what our logic tells us, the shortest route between points A and B is rarely a straight line in our life. It is circuitous and winding and sometimes even seems to go backwards.

The 'fast path' has obstacles in the way we are unaware of. Guided by inner wisdom we circumvent these. The picture below shows this:

The dotted line is a simplified version of the path we take.

Also yes, you can, if you so desire - dictate the "how's and who's" of it.

I urge you to consider carefully why you might desire to do that though.

I often find when I feel compelled to do that it is because I am not being entirely honest about what my real desires are and my reasons behind them.

It also can set up a load of resistance which can put a brake on manifestation.

It places our limited viewpoints on situations, effectively undermining our inner wisdom with our thinking we know best and our excessive desire to control.

We will still get there though, provided we can ease resistance. Our inner being is definitely capable...and we're even given chances repeatedly when we are so foolish as to miss them. :)

Sometimes we just want to experience a specific journey to the destination though. That's cool. I definitely do it myself and I'm sure others here do too. Keep in mind that you're in it for the journey though in that case (we really always are anyway)...because it is unlikely to be the fastest way.
