Acharya Prashant explains the concepts of the knower, the known, and knowledge, as discussed in the Ashtavakra Gita. He defines the 'known' as anything the mind can perceive or cognize, the 'knower' as the internal entity that claims to know, and 'knowledge' as the relationship between the two. He notes that the ego typically attaches itself to the role of the knower, becoming dependent on the objects of the known. This dependency leads to bondage and suffering because the objects of the world are transient and beyond one's control. When these objects are lost or fail to provide satisfaction, the result is misery, restlessness, or disappointment.
