The technique of positive thinking is not a technique that transforms you. It is simply repressing the negative aspects of your personality. It is a method of choice. It cannot help awareness; it goes against awareness. Awareness is always choiceless.
We all have choices that we are empowered to make on a daily basis, and while those choices can be limited by affordability and accessibility, we still have the opportunity to make our best choice. That best choice usually requires more effort and more thought, but, undeniably, the results are worth it.
In awareness there is no becoming, there is no end to be gained. There is silent observation without choice and condemnation, from which there comes understanding.
