Although it is effortless to be MF, it takes effort to remember to be mindful. The practice of recollection; remembering that which is most true to our hearts.
In dealing with the demons of the mind that is with all the emotions and mental states causing fear, sorrow, attachment or any other sort of mental anquish we are able to courageously face them with bare awareness. When this awareness or mindfulness is strong without reacting to the experience, even the worst enemies are dissolved like the morning mist in the rising sun.
