Ashtavakra Gita 18.28 -

Though ‘Subject-knowledge’ and ‘object-knowledge’ are both knowledge, there is a fundamental difference between the two. Any knowledge of objects makes one competent enough to deal with and apply the objects for different purposes. For instance, you see a footpath before you. In the light of your vision, you start walking on it. Seeing a pen on your table, you take it and start writing whatever you want. In both cases, we are utilizing the object for whatever purpose we have in mind.

The Subject-knowledge is not so. Brahma-vid brahmaiva bhavati (Mundakopanishad 3.2.9 ). One who knows Brahman becomes Brahman. The seeker first comes to know about his Self, he probes into the matter more. Finally he takes to introspection and ultimately, the knowledge that he is the Self, makes him the Self indeed. This is the distinction of Subject-knowledge.

Sage Ashtavakra says that the exalted soul, the Knower, drops all ideas of distraction and the causes for it. Once he knows the fallacy of distraction, where is the need for him to pursue meditation or samadhi? Equally so, there being no distant goal for him to attain, he drops the idea of seeking itself. As a result, even the least feeling of any bondage vanishes from him. The entire creational display proves to be an imagination or super-imposition. With that he becomes Brahman indeed!
