<Distorted view through dirty sunglasses of "me".>                                 In such a situation, efforts that only focus on making external changes are similar to trying to make a room brighter by installing more light fixtures while continuing to wear cheap, dirty sunglasses which darken and distort one's vision. Rather than only increasing the number of lights, it would be more essential to clean the dirt from the lenses or simply take the sunglasses off. But, unlike sunglasses, ego-consciousness is very deep-rooted in our mind and it cannot be easily "cleaned" or removed. It requires a long and constant process of internal improvement to clean up our mind and remove the self-centered force of our ego.
