The problem of 'how we know that we know something' (cognition of cognition) has seldom been dealt with by Western philosophers. It is an important problem for many aspects of life and thought. Pandit Vishwabandhu in this book gives us a comprehensive solution to this problem.
Always discriminate -- your body, your house, the people around, and the world are all unreal like a dream. Always think that this body is only an inert instrument. And the Atman within is your real nature.
-Swami Vivekananda
