Nisargadatta, Consciousness and the Absolute

You must have a thorough knowledge of this consciousness, and having known everything about the consciousness you come to the conclusion that it is all unreal, and then it should drop off. Having listened to these talks, sit and meditate, "That which I have heard, is it true or not?" Then you will understand that this is also to be discarded.
