Knowledge is some experience, theories created by others and traditions of the society. These are required to practice our profession or earn the living. Inwardly one has to abandon the knowledge to see the reality. As Patanjali Rishi says "Yogassa Chitta Viritti Nirodaha". This gradually ceasing wave of modifications of the mind finally lead to enlightenment. In this Samadhi the concept and the concept creator is eliminated.
