Brooding over impure thoughts adds to their evil force. Do not become prey to these haunting dangerous thoughts. Entertain counter-thoughts: good sublime thoughts of God and His Divine Glory. By Japa, fasting, charity and selfless service, you can easily destroy the impurities of the complex mind. The evil thoughts, for lack of attention and by the pressure of good thoughts, will die a natural death.
