Acharya Prashant explains that expectation arises from a deep sense of incompleteness and a feeling that something is missing from life. This inner lack of fulfillment leads individuals to expect things from the world, others, and themselves. Because people do not understand the true nature of this gap, they attempt to fill it with useless things and fake treatments. Expectation from others, including from one's children, is one such false treatment that fails to address the real disease of inner incompletion.
