Acharya Prashant explains that what is commonly referred to as positive thinking is merely a projection of one's own thoughts and past knowledge onto a situation, which often leads to delusion rather than truth. He argues that both positive and negative thinkers are equally disconnected from reality because they are limited by their past experiences and cannot think beyond what they already know. Instead of being trapped in these mental projections, one should strive to know the reality of the present moment. Real positivity, according to him, is found in knowing, joy, freedom, and love, rather than in make-believe thoughts or dreams.
