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.
Salvation is from our side a choice, from the divine side it is a seizing upon, an apprehending, a conquest by the Most High God. Our 'accepting' and 'willing' are reactions rather than actions. The right of determination must always remain with God.
