Arielle: In addition to healing your heart from past relationships, you need to create a clear intention.  The analogy I like to use it this: When you walk into your favorite coffee hangout what is the first thing you do?  Place your order.  You confidently tell the barista, “I will have a tall, half-caff, low-fat mocha latte, with a splash of non-sugar vanilla syrup to go.”  The barista smiles, writes your order on the side of a cup and takes your money.  Within minutes you are walking out the door with the precise, delicious cup of coffee that you ordered.  Ordering up a soul mate from the Universe works in a similar way.  It’s not always as instantaneous but it can be just as precise. But to have the Universe to deliver your perfect soul mate, you must first clearly place your order. This isn’t quite as easy as it sounds. You must first search your heart for what you really, really desire. By now you know what you don’t want but you need to ask for what you do want.  In the Soulmate Kit we explain how to place your order by creating a detailed list and we then provide a variety of rituals to do to release your list to the Universe.
The universe hears your intentions, but when you’re unclear about what you want, you’ll get an equally unclear answer, or worse, something you don’t actually want. Only you know what’s best for you, and your spirit guides can help you get there – you just have get into a deep quiet to listen to their messages. Putting down what you want in writing also helps clarify your visions. The more detailed, the better.

You claim that "positive thoughts always resulting in positive things" is not the basis of the LOA. In part you are correct. The foundational basis in science, as I alluded to in the article was that thought stuff particles travel through ether (not air) and interact with formless stuff to create whatever it is that you are thinking about. This was how "the law" started.
