If you think about why you want the physical manifestation, it's to feel better.

There's simply nothing we could ever want physically in our lives that is for any other reason that we think that, once we've received it, we'll feel better.

Try and find something that contradicts this idea - you won't :) Even "selfless" acts like helping others make us feel better... we are actually selfless for selfish reasons :)

So when you have reached the vibrational place regarding what you want physically that you already feel better because you know you will receive it, you've actually already reached the point that the physical manifestation would have brought you to anyway.

You might have to read that last sentence a few times because it contains a hugely important concept :)

The reason you feel disappointed is that you are judging your success by whether or not you can observe the physical manifestation in your reality... because you are effectively telling yourself that once you can observe it physically, you will then allow yourself to feel better.

But that's a painful way to live, even though most of humanity chooses to live that way.

A better judge of success would be whether you already feel better because of your vibrational work.

In other words, once you make the good-feeling emotion the end-manifestation and leave it at that, you'll not only get right now what the physical manifestation would have originally brought you but, almost paradoxically, you are also in the best possible place to allow the physical manifestation to happen also

You'll also realize that the physical manifestation is actually irrelevant because you already feel better even when you don't have it :)

And eventually you'll reach the point where you realize that physical manifestations have no purpose but to give us a reason to focus to feel better :)

BOTTOM LINE:
Treat the positive emotion as the manifestation...and everything will take care of itself
