The indicator of true knowledge is the ability to differentiate what uplifts us from what pulls us down.
Make use of radio, TV and films discriminatively; only for programs that will enhance our knowledge and culture. Television is tele-visham (tele-poison, in Malayalam). If we are not careful, it can corrupt our culture, damage our eyes and drain away our time.
Just as armor protects the soldier, spiritual knowledge protects us from the difficulties of life.
