There isn't an easy way. But there is a way. It is slow but it is definite & really works. It requires a picture of understanding of your inner consciousness. The picture doesn't have to be "right" or accurate. You can invent your own "picture of understanding".

I'm still at work (but couldn't resist peeking in here); I'll expand my answer when I get home.

(Added later) Ok, here goes... You need to draw yourself a picture of a tree or get a simple line drawing of a tree, the type with many twisted branches & small leaves at the ends of the branches. The picture is irrelevant, but to hold the idea in your head it helps.

This tree is a representation of your consciousness. Ignore the bottom part of the tree (the roots etc). The trunk of the tree represents your point of reference in consciousness or the main artery of consciousness. Now look at those branches. They represent main ideas that are part of your personality make-up. We are talking about belief systems. Now look at those leaves at the end. Each leaf is an individual idea that you have accepted as the “truth” about yourself and allowed this idea to become the basis of your personality.

Each leaf is an experience, or lesson, or belief that you have accepted as the “truth” in the moment you experienced that event. So, for example, when you were growing up you enjoyed playing in the rain or walked home from school deliberately in the rain, enjoying the experience of getting soaked. But when you got home you were disciplined by your parents who made it clear that you will get sick because of your wet clothes.

Now this memory is deeply embedded as an idea in your psyche as just one leaf of this “tree of consciousness”. The idea is “If I get wet, I will be sick”. Every lesson learned, Every incident experienced, every thought contemplated, every conversation engaged, contributes to the continuing growth & nurturing of this tree of understanding.

Now the branches of the tree are groupings of thought forms. So, there would be a branch representing all things to do with illness, a branch for ideas of success, & so-on.

With time you forget the details or the exact “consciousness” of each leaf. It is deeply embedded within your psyche & is forming you current personality.

Now draw a large arrow on the side of the tree to represent a wind blowing towards the tree. This wind represents pure creative consciousness, or the energy of creation, in the form of un-limited potential blowing towards your tree of consciousness.

As this wind blows it shakes the tree and the leaves. The leaves vibrate in this wind of opportunity & depending on the moment, certain leaves of the tree will vibrate in resonant harmony with this wind of opportunity. In other words, if there is an opportunity in this wind of un-limited potential to manifest the experience of any of your leaves in your tree of consciousness, it will resonate with the wind and you will spontaneously find your self thinking a thought. It is the explosion of un-limited potential giving you the chance to participate in the materialization of your belief system into manifested reality.

Simply put, when you suddenly start thinking something or worrying about something, it is because the opportunity to materially manifest that “worry” or “thought-form” is becoming available & you are being given a chance to participate in the Living or materializing of that thought or worry.

So you always have Un-limited potential available to you, but it effortlessly manifests or allows you to effortlessly participate in what you already believe to be true.

Now you can ignore this existing make-up of your personality & start changing by attracting what you want with the law of attraction. But over time you will find that when you are not working on attracting what you want, you fall back to the same place as before. It’s like, you have to constantly keep your foot on the gas pedal of the law of attraction, & the moment you let go you are back to being the same person.

This is not because the law of attraction doesn’t work. It’s because the law of attraction is always working. Its attraction is constantly on. It’s working from the blueprint of your tree of consciousness. So you don’t have a lack of ability to attract, rather you are an expert in attracting everything you want. But most of what you are attracting is buried deep within your consciousness.

This is why the first instruction in this journey is “Know Thy Self”. This is a lifelong journey with no destination. So don’t get frustrated with your lack of progress. There is no destination against which you can measure your progress. Where ever you are at, is where you are supposed to be.

Work on discovering who you are & what you believe in. There is no good or bad here, only cause & effect. So don’t feel bad about parts of your personality that correspond to the idea of “Bad”. Examine & let-go what doesn’t serve you, but understand that if you were meant to be a saint, you would not be on this earth. You are here to learn from contrast and, dare I say, Imperfections of personality.

I want to expand on this much more but I don’t want to write an entire book here. So see if this information is relevant to your situation. I wrote this information down for my own benefit of awakening. I am a student just like you. Just because I got this answer doesn’t mean I have mastered this area. On the contrary, this is the area I have been working on (within myself) for the last 20 years. Remember, there is no destination. Only the journey.

(Follow up) I just added the rest of what I wanted to say here as the response to the question "How is the “attention” used in manifestation? Or is it used?” So feel free to continue on to that question. It’s more of the same answer but from a different view.
