Book by the learned teacher and saint Nithyachaithanya Yati. Deals with the mind in diseased state mainly, intended for common man for clearing his usual doubts. Even though its in Malalyalam, its a little hard one to digest due to his hard prose in some places. But really interesting and adding of his own personal experiences was really informative.
