In our highly technologically evolved society where we have immediate access to almost everuhings that is happening around our planet, we are bombarded with thoughts and ideas that, at times, feel invasive to our personal experience. And so, the idea of controlling your thoughts when there are so many other thoughts coming forth seems impossible. It seems, instead, rather normal to just give your attention to whatever is in front of you.
We are not encouraging you to make an effort to control your thoughts, but instead, to make an effort to, more or less, guide your thoughts. And it is not even so much about guiding your thoughts as it is about reaching for a feeling, because reaching for the way you would like to feel is an easier way to hold your thoughts in vibrational alignment with that which you believe is good.
The Law of Attraction is already magnetically attracting and organising your thoughts, so having an understanding of, and deliberately working with the Law of Attraction is extremely helpful in an effort at guiding your own thoughts.
Remember, whenever you give your attention to a thought, that thought immediately becomes activated within you, so the Law of Attraction immediately responds, which means that other thoughts, in vibrational harmony with the thought that you have just activated, now join your activated thought, making it a more pronounced, more powerful, and more attractive thought. And as you continue your focus, and as your thought expands, that more powerful thought that you have just activated is joined by others like it and on it goes.
