Acharya Prashant explains that craving is the fundamental incompleteness and the basic knot of the heart, acting as the mother of everything except God. He describes craving as God's joke upon himself, where the totality manifests as limited entities seeking to return to that totality. This craving expresses itself through the mind, sense organs, and all human actions, yet it can never be fulfilled by worldly things because the world itself is a result of craving. Only that which is deeper than craving, which is God, can provide true fulfillment. Man often fails because he attempts to quench this thirst through material means and companions, which are shallower than the root of the desire. He further elaborates on the role of self-conceit, which the Buddha identifies as the father. Self-conceit is a misplaced confidence that prevents an individual from admitting they are moving in the wrong direction. It is a high self-image that makes it intolerable for a person to accept that their entire approach to life has been a mistake. While one might admit to making a mistake, self-conceit prevents the realization that one's very existence and direction are fundamentally flawed. This ego-driven certainty leads to more industrious efforts in the wrong direction rather than a humble redirection toward the truth.
