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.
Look here -- we shall die! Bear this in mind always, and then the spirit within will wake up. Then meanness will vanish from you, practicality in work will come, you will get new vigor in mind and body, and those who come in contact with you will also feel that they have really got something uplifting from you.
-Swami Vivekananda
